Prioritizing software right to repair: engaging corporate response teams

by Denver Gingerich on February 3, 2024

Across organizations who develop and deploy software, there are a wide range of time-sensitive concerns that arise. Perhaps the most diligent team that responds to such time-sensitive concerns is the cybersecurity team. It is crucial for them to quickly understand the security concern, patch it without introducing any regressions, and deploy it. In extreme cases this is all done within a few hours — a monumental task crammed into less time than a dinner party (and often replacing such a social event at the last minute; these teams are truly dedicated).

Many other teams exist across organizations for different levels of risk and concern. In our experience, on average among many companies, the team that receives among the lowest priorities is the team that responds to concerns about a company's copyleft compliance. Now we can think of some reasons for this: the team is often not connected to the team that collated the software containing copylefted code, or that latter team was not given proper instruction for how to comply with the licenses (and/or does not read the licenses themselves). So the team responding when someone notes a copyleft compliance deficiency is ill-equipped to handle it, and is often stonewalled by developer teams when they ask them for help, so the requests for correct source code under copyleft licenses usually languish.

With this in mind, we at SFC are helping prioritize the copyleft compliance concerns an organization may face due to some of the above. To reflect the importance of teams responding to copyleft compliance concerns, we recommend that companies create a team that we are calling a "Copyleft Compliance Incident Response Team" (CCIRT). This will help convey to management the importance of properly staffing the team, but also how it must be taken seriously by other teams that the CCIRT relies on to respond to incidents. Where companies employ Compliance Officers, they will likely be obvious leaders for this team.

Now some companies may not need a CCIRT. Unlike security vulnerabilities, failing to comply with copyleft licenses is entirely preventable. If you know your company already has policies and procedures that yield compliant results (of the same form as compliant source candidates that we praise in the comments on Use The Source), then there is no need for a CCIRT. However, our experience shows that most companies do not have such policies and procedures, in which case a CCIRT is necessary until such policies and procedures can reliably produce compliant source candidates from the start.

We recently launched Use The Source (alluded to above), which helps device owners and companies see whether source code candidates (the most important part of copyleft compliance) are giving users their software right to repair, i.e. whether they comply with the copyleft licenses they use. We realize companies may be concerned about SFC publishing their source candidates before they have had a chance to double-check them for compliance, due to some of the issues with policies and procedures mentioned above. As a result, we are giving companies the opportunity to be notified before we post a source candidate of theirs, so that they can take up to 7 days to update the candidate with any fixes they feel may be necessary before we post it. And the sooner a company contacts us, the better, as we are offering up to 37 days from the launch of Use The Source before we publish candidates we receive. See our CCIRT notification timeline for details. For historical purposes, the additional grace period that we provided at launch time is detailed here.

We hope that this new terminology will help organizations prioritize copyleft compliance appropriately, and that everyone can benefit from the shared discussions of source candidates and their compliance with copyleft licenses. We look forward to working with companies and device owners to promote exceptional examples of software right to repair (through our comments on Use The Source) as we find them.

How I watched a Motion for Summary Judgment hearing

by Denver Gingerich on October 12, 2023

In SFC's ongoing lawsuit against Vizio asking to receive the source code for the copylefted components on their TVs, last week we had a hearing with the judge to discuss the Motion for Summary Judgment that Vizio filed (requesting that the court reject our case before it even went to trial). A couple of our staff attended in-person (in an Orange County courthouse in Southern California) while others, like myself, watched remotely.

I was hoping to be able to use a standard interface to view the proceedings (such as streaming video provided to a <video/> element on a webpage), but unfortunately that was not available. The only way to view hearings in this court remotely is via Zoom, which SFC has talked about recently. This presented me with a conundrum - do I join via Zoom to see what was said? Or am I prevented from accessing this civic discourse because the court chooses not to use a standard video sharing method, preventing a large segment of society from taking part? As part of their normal practice, the court does not record (nor allow recording except through an official court reporter that can be hired by the parties to take a textual transcript) of proceedings, so I needed to decide with some urgency how to proceed, as failing to join now would mean I couldn't see the hearing at all, neither now nor in the future.

I am not sure how other countries approach this problem, and maybe it is no different elsewhere, but it did concern me deeply how this technical decision to demand the use of proprietary software could leave so many people disenfranchised, both with respect to their legal system, and other public services as well.

As part of SFC's policy to allow the use proprietary software if it is critical to our mission, I decided that it was more important for me to be able to view the proceedings (and avoid charging many hundreds of dollars to SFC for an international flight and hotel). Note that SFC would never require this of me, and would gladly pay for me to attend in-person to avoid the proprietary software, but I felt personally it was the right decision for me to make in this context.

Once this dilemma was resolved (for better or worse), I went through the technical steps required to join the Zoom call for the court hearing, where I was presented with this text:

By clicking "Join", you agree to our {0} and {1}.

Now there were no links to {0} or {1}, so I made some guesses as to what I was agreeing to. In the best case, I was agreeing to nothing, and in the worst case I was agreeing that 0 and 1 provided the foundation for all humanity which, while potentially troubling, did have a certain appeal as a technologist. In any case, I clicked Join (possibly leaving an indelible mark on the future of the universe) and was at last able to observe the hearing, after dialing in by (SIP) phone for the audio, to reduce the amount of proprietary code being run for me to view the hearing.

The hearing event itself was familiar to those who have attended such court proceedings - there were many other cases heard that day, that touched on issues such as whether you could get a DUI while riding a horse (answer: yes), to much more serious and unfortunate clear instances of DARVO tactics in domestic disputes (which we hope will not ultimately sway the judge). It appeared the judge wanted to save our hearing for last, possibly due to its complexity or novelty. The lawyers in most of the other matters appeared remotely.

Once the other cases were heard, the judge turned to us, with both our lawyers and Vizio's lawyer physically present in the courtroom. She asked Vizio to go first (since it was Vizio's motion), and their lawyer went over the points from their Motion for Summary Judgment, eventually clarifying seven specific objections Vizio had made to our case in its motion - the judge had clearly read our brief and wanted to know more on these seven topics given how we addressed them.

It was a bit jarring to hear my own name mentioned in court, as one of the objections was to an email I had sent to Vizio when we informed them they were violating the GPL. While not a problem for our case, it reminded me of the need to be extra careful, since anything we say to a company who violates the GPL can end up in court. But it also reminded me of why it is important we do this: if people feel scared to file lawsuits when companies fail to comply with the software freedom licenses they choose to use, then we at SFC must step up and use our resources and substantial experience to make sure the unfounded claims by companies of how they should be able to get away with violating are firmly rebuffed.

After Vizio's lawyer had finished, the judge turned to our lawyers for a response. Our lawyers presented an excellent litany of reasons why SFC's case is not preempted by copyright (for example, there is an extra element, provision of source code, that copyright remedies do not provide), and why we have rights as a third-party to the GPL contract between Vizio and the developers of the software that Vizio chose to use (as an example, the GPL itself clearly states, "You [Vizio] must make sure that they [third-party recipients such as SFC], too, receive or can get the source code").

Our lawyers finished with some examples of how contract law works, where if you agree to make some copies, but don't pay the money required in the contract, then that's a contract claim, not a copyright claim. In that case, a party has stiffed the beneficiary on the money. And in our case, as our lawyer so eloquently ended the hearing: "Vizio has stiffed us on the code".

We are extremely proud of our lawyers in this case, especially the two lawyers who argued in-person for us on Thursday: Naomi Jane Gray and Don Thompson, as well our General Counsel Rick Sanders. Whether companies are held accountable for following the software right to repair licenses they choose to use is immensely important - they need to give us the same rights they have, and we're incredibly happy that our legal team are so laser-focused on this.

We look forward to hearing the judge's decision on this motion when it comes out (in the meantime, you can read the hearing transcript if you like). Whatever the result, we will keep fighting for your software rights, everywhere software is used, using the legal mechanisms available (when required), to make sure everyone can control their technology.

RHEL Panel Discussion at FOSSY 2023

by Bradley M. Kuhn on July 19, 2023

This past weekend, July 13-16th, 2023, Software Freedom Conservancy (SFC) hosted and ran a new conference, FOSSY (Free and Open Source Software Yearly) in Portland, Oregon, USA. I was glad to host the keynote panel discussion on the recent change made by Red Hat (now a subsidiary of IBM) regarding the public source code releases for Red Hat Enterprise Linux (RHEL).

The panelists included (in alphabetical order) Jeremy Alison, software engineer at CIQ (focused on Rocky Linux) and Samba co-founder, myself, Bradley M. Kuhn, policy fellow at SFC, benny Vasquez, the Chair of the AlmaLinux OS Foundation, and James (Jim) Wright, who is Oracle’s Chief Architect for Open Source Policy, Strategy, Compliance, and Alliances.

Red Hat themselves did not reply to our repeated requests to join us on this panel, but we were able to gather the key organizations impacted by Red Hat's recent decision to cease public distribution of RHEL sources. SUSE was also invited but let us know they were unable to send someone on short notice to Portland for the panel.

We're very glad to make the video available to everyone who has been following this evolving story. FOSSY is a new event, and we've hopefully shown how running a community-led FOSS event here in Portland each summer creates an environment where these kinds of important discussions can be held to explore issues impacting FOSS users around the world.

I thank our panelists again for booking last-minute travel to be with us for this exciting panel and thank all the FOSSY attendees for their excellent questions during the panel.

I hope to see all of you at next years' FOSSY!

A Comprehensive Analysis of the GPL Issues With the Red Hat Enterprise Linux (RHEL) Business Model

by Bradley M. Kuhn on June 23, 2023

This article was originally published primarily as a response to IBM's Red Hat's change to no longer publish complete, corresponding source (CCS) for RHEL and the prior discontinuation of CentOS Linux (which are related events, as described below). We hope that this will serve as a comprehensive document that discusses the history of Red Hat's RHEL business model, the related source code provisioning, and the GPL compliance issues with RHEL.


For approximately twenty years, Red Hat (now a fully owned subsidiary of IBM) has experimented with building a business model for operating system deployment and distribution that looks, feels, and acts like a proprietary one, but nonetheless complies with the GPL and other standard copyleft terms. Software rights activists, including SFC, have spent decades talking to Red Hat and its attorneys about how the Red Hat Enterprise Linux (RHEL) business model courts disaster and is actively unfriendly to community-oriented Free and Open Source Software (FOSS). These pleadings, discussions, and encouragements have, as far as we can tell, been heard and seriously listened to by key members of Red Hat's legal and OSPO departments, and even by key C-level executives, but they have ultimately been rejected and ignored — sometimes even with a “fine, then sue us for GPL violations” attitude. Activists have found this discussion frustrating, but kept the nature and tenure of these discussions as an “open secret” until now because we all had hoped that Red Hat's behavior would improve. Recent events show that the behavior has simply gotten worse, and is likely to get even worse.

What Exactly Is the RHEL Business Model?

The most concise and pithy way to describe RHEL's business model is: “if you exercise your rights under the GPL, your money is no good here”. Specifically, IBM's Red Hat offers copies of RHEL to its customers, and each copy comes with a support and automatic-update subscription contract. As we understand it, this contract clearly states that the terms do not intend to contradict any rights to copy, modify, redistribute and/or reinstall the software as many times and as many places as the customer likes (see §1.4). Additionally, though, the contract indicates that if the customer engages in these activities, that Red Hat reserves the right to cancel that contract and make no further contracts with the customer for support and update services. In essence, Red Hat requires their customers to choose between (a) their software freedom and rights, and (b) remaining a Red Hat customer. In some versions of these contracts that we have reviewed, Red Hat even reserves the right to “Review” a customer (effectively a BSA-style audit) to examine how many copies of RHEL are actually installed (see §10) — presumably for the purpose of Red Hat getting the information they need to decide whether to “fire” the customer.

Red Hat's lawyers clearly take the position that this business model complies with the GPL (though we aren't so sure), on grounds that that nothing in the GPL agreements requires an entity keep a business relationship with any other entity. They have further argued that such business relationships can be terminated based on any behaviors — including exercising rights guaranteed by the GPL agreements. Whether that analysis is correct is a matter of intense debate, and likely only a court case that disputed this particular issue would yield a definitive answer on whether that disagreeable behavior is permitted (or not) under the GPL agreements. Debates continue, even today, in copyleft expert circles, whether this model itself violates GPL. There is, however, no doubt that this provision is not in the spirit of the GPL agreements. The RHEL business model is unfriendly, captious, capricious, and cringe-worthy.

Furthermore, this RHEL business model remains, to our knowledge, rather unique in the software industry. IBM's Red Hat definitely deserves credit for so carefully constructing their business model such that it has spent most of the last two decades in murky territory of “probably not violating the GPL”.

Does The RHEL Business Model Violate the GPL Agreements?

Perhaps the biggest problem with a murky business model that skirts the line of GPL compliance is that violations can and do happen — since even a minor deviation from the business model clearly violates the GPL agreements. Pre-IBM Red Hat deserves a certain amount of credit, as SFC is aware of only two documented incidents of GPL violations that have occurred since 2006 regarding the RHEL business model. We've decided to share some general details of these violations for the purpose of explaining where this business model can so easily cross the line.

In the first violation, a large Fortune 500 company (which we'll call Company A), who both used RHEL internally and also built public-facing Linux-based products, decided to create a consumer-facing product (which we'll call Product P) based primarily on CentOS Linux, but P included a few packages built from RHEL sources. Company A did not seek nor ask for support or update services for this separate Product P. Red Hat later became aware that Product P contained some part of RHEL, and Red Hat demanded royalty payments for Product P. Red Hat threatened to revoke the support and update services on Company A's internal RHEL servers if such royalties were not paid.

Since Company A was powerful and had good lawyers and savvy business development staff, they did not acquiesce. Company A ultimately continued (to our knowledge) on as a RHEL customer for their internal servers and continued selling Product P without royalty payments. Nevertheless, a demand for royalties for distribution is clearly a violation as that demand creates a “further restriction” on the permissions granted by GPL. As stated in GPLv3:

You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License.

Red Hat tried to impose a further restriction in this situation, and therefore violated the GPL. The violation was resolved since no royalty was paid and Company A faced no consequences. SFC learned of the incident later, and informed Red Hat that the past royalty demand was a violation. Red Hat did not dispute nor agree that it was a violation, and did informally agree such demands would not be made in future.

In another violation incident, we learned that Red Hat, in a specific non-USA country, was requiring that any customer who lowered the number of RHEL machines under service contract with Red Hat sign an additional agreement. This additional agreement promised that the customer had deleted every copy of RHEL in their entire organization other than the copies of RHEL that were currently contracted for service with Red Hat. Again, this is a “further restriction”. The GPL agreements give everyone the unfettered right to make and keep as many copies of the software as they like, and a distributor of GPL'd software may not require a user to attest that they've deleted these legitimate, licensed copies of third-party-licensed software under the GPL. SFC informed Red Hat's legal department of this violation, and we were assured that this additional agreement would no longer be presented to any Red Hat customers in the future.

In both these situations, we at SFC were worried they were merely a “tip of the proverbial iceberg”. For years, we have heard from Red Hat customers who are truly confused. It's common in the industry to talk about RHEL “seat licenses”, and many software acquisition specialists in the industry are not aware of the nuances of the RHEL business model and do not understand their rights. We remain very concerned that RHEL salespeople purposely confuse customers to sell more “seat licenses”. It's often led us to ask: “If a GPL violation happens in the woods, and everyone involved doesn't hear it, how does anyone know that software rights have indeed been trampled upon in those woods?”. As we do for as many GPL violation reports as we can, we zealously pursue RHEL-related GPL violations that are reported to us, and if you're aware of one, please do email us at <compliance@sfconservancy.org> immediately. We fear that be it through incompetence or malice, many RHEL salespeople and business development professionals may regularly violate GPL and no one knows about it. That said, the business model as described by IBM's Red Hat may well comply with the GPL — it's just so murky that any tweak to the model in any direction seems to definitely violate, in our experience.

Furthermore, Red Hat exploits the classic “caveat emptor” approach — popular in many a shady business deal throughout history. While, technically speaking, a careful reader of the GPL and the RHEL agreements understands the bargain they're making, we suspect most small businesses just don't have the FOSS licensing acumen and knowledge to truly understand that deal.

Why Was an Independent CentOS So Important?

Until Red Hat's “aquisition” of CentOS in early 2014, CentOS provided an excellent counterbalance to the problems with the RHEL business model. Specifically, CentOS was a community-driven project, with many volunteers, supported by some involvement from small businesses, to re-create RHEL releases using the CCS releases made for RHEL. Our pre-2014 view was that CentOS was the “canary in the murky coalmine” of the RHEL business. If CentOS seemed vibrant, usable, and a viable alternative to RHEL for those who didn't want to purchase Red Hat's updates and services, the community could rest easy. Even if there were GPL violations by Red Hat on RHEL, CentOS' vibrancy assured that such violations were having only a minor negative impact on the FOSS community around RHEL's codebase.

Red Hat, however, apparently knew that this vibrant community was cutting into their profits. Starting in 2013, Red Hat engaged in a series of actions that increased their grip. First, they “acquired” CentOS. This was initially couched as a cooperation agreement, but Red Hat systematically made job offers that key CentOS volunteers couldn't refuse, acquired the small businesses who might ultimately build CentOS into a product, and otherwise integrated CentOS into Red Hat's own operations.

After IBM acquired Red Hat, the situation got worse. Having gotten rights to the CentOS brand as part of the “aquisition”, Red Hat slowly began to change what CentOS was. CentOS Linux quickly ceased to be a check-and-balance on RHEL, and just became a testing ground for RHEL. Then, in 2020, when most of us were distracted by the worst of the COVID-19 pandemic, Red Hat unilaterally terminated all CentOS Linux development. Later (during the Delta variant portion of the pandemic in late 2021) Red Hat ended CentOS Linux entirely. IBM's Red Hat then used the name “CentOS Stream” to refer to experimental source packages related to RHEL. These were (and are) not actually the RHEL source releases — rather, they appear to be primarily a testing ground for what might appear in RHEL later.

Finally, Red Hat announced two days ago that RHEL CCS will no longer be publicly available in any way. Now, to be clear, the GPL agreements did not obligate Red Hat to make its CCS publicly available to everyone. This is a common misconception about GPL's requirements. While the details of CCS provisioning vary in the different versions of the GPL agreements, the general principle is that CCS need to be provided either (a) along with the binary distributions to those who receive, or (b) to those who request pursuant to a written offer for source. In a normal situation, with no mitigating factors, the fact that a company moved from distributing CCS publicly to everyone to only giving it to customers who received the binaries already would not raise concerns.

In this situation, however, this completes what appears to be a decade-long plan by Red Hat to maximize the level of difficulty of those in the community who wish to “trust but verify” that RHEL complies with the GPL agreements. Namely, Red Hat has badly thwarted efforts by entities such as Rocky Linux and Alma Linux. These entities are de-facto the intellectual successors to CentOS Linux project that Red Hat carefully dismantled over the last decade. These organizations sought to build Linux-based distributions that mirrored RHEL releases, and it is now unclear if they can do that effectively, since Red Hat will undoubtedly capriciously refuse to sell them exactly-one RHEL service and update “seat license” at a reasonable price. It appears that, as of this week, one must have at least that to get timely access to RHEL CCS.

What Should Those Who Care About Software Rights Do About RHEL?

Due to this ongoing bad behavior by IBM's Red Hat, the situation has become increasingly complex and difficult to face. No third party can effectively monitor RHEL compliance with the GPL agreements, since customers live in fear of losing their much-needed service contracts. Red Hat's legal department has systematically refused SFC's requests in recent years to set up some form of monitoring by SFC. (For example, we asked to review the training materials and documents that RHEL salespeople are given to convince customers to buy RHEL, and Red Hat has not been willing to share these materials with us.) Nevertheless, since SFC serves as the global watchdog for GPL compliance, we welcome reports of RHEL-related violations.

We finally express our sadness that this long road has led the FOSS community to such a disappointing place. I personally remember standing with Erik Troan in a Red Hat booth at a USENIX conference in the late 1990s, and meeting Bob Young around the same time. Both expressed how much they wanted to build a company that respected, collaborated with, engaged with, and most of all treated as equals the wide spectrum of individuals, hobbyists, and small businesses that make the plurality of the FOSS community. We hope that the modern Red Hat can find their way back to this mission under IBM's control.
