Software Freedom Ensures the True Software Commons

by Bradley M. Kuhn on August 22, 2018

Proprietary software has always been about a power relationship. Copyright and other legal systems give authors the power to decide what license to choose, and usually, they choose a license that favors themselves and takes rights and permissions away from others.

The so-called “Commons Clause” purposely confuses and conflates many issues. The initiative is backed by FOSSA, a company that sells materiel in the proprietary compliance industrial complex. This clause recently made news again since other parties have now adopted this same license.

This proprietary software license, which is not Open Source and does not respect the four freedoms of Free Software, seeks to hide a power imbalance ironically behind the guise “Open Source sustainability”. Their argument, once you look past their assertion that the only way to save Open Source is to not do open source, is quite plain: If we can't make money as quickly and as easily as we'd like with this software, then we have to make sure no one else can as well.

These observations are not new. Software freedom advocates have always admitted that if your primary goal is to make money, proprietary software is a better option. It's not that you can't earn a living writing only Free Software; it's that proprietary software makes it easier because you have monopolistic power, granted to you by a legal system ill-equipped to deal with modern technology. In my view, it's a power which you don't deserve — that allows you to restrict others.

Of course, we all want software freedom to exist and survive sustainably. But the environmental movement has already taught us that unbridled commerce and conspicuous consumption is not sustainable. Yet, companies still adopt strategies like this Commons Clause to prioritize rapid growth and revenue that the proprietary software industry expects, claiming these strategies bolster the Commons (even if it is a “partial commons in name only”). The two goals are often just incompatible.

Here at Conservancy, we ask our projects to be realistic about revenue. We don't typically see Conservancy projects grow at rapid rates. They grow at slow and steady rates, but they grow better, stronger, and more diverse because they take the time to invite everyone to get involved. The software takes longer to mature, but when it does it's more robust and survives longer.

I'll take a bet with anyone who'd like. Let's pick five projects under the Affero GPL and five projects under the Commons Clause, and then let's see which ones survive longer as vibrant communities with active codebases and diverse contributors.

Finally, it's not surprising that the authors chose the name “Commons”. Sadly, “commons” has for many years been a compromised term, often used by those who want to promote licenses or organizational models that do not guarantee all four freedoms inherent in software freedom. Proprietary software is the ultimate tragedy of the software commons, and while it's clever rhetoric for our opposition to claim that they can make FOSS sustainable by proprietarizing it, such an argument is also sophistry.

Congratulations to Tesla on Their First Public Step Toward GPL Compliance

by Bradley M. Kuhn and Karen M. Sandler on May 18, 2018

Conservancy rarely talks publicly about specifics in its ongoing GNU General Public License (GPL) enforcement and compliance activity, in accordance with our Principles of Community Oriented GPL Enforcement. We usually keep our compliance matters confidential — not for our own sake — but for the sake of violators who request discretion to fix their mistakes without fear of public reprisal. As occurred a few years ago with Samsung, we're thrilled when a GPL violator decides to talk about their violation and works to correct it publicly. This gives us the opportunity to shine light on the real-world work of GPL and copyleft compliance.

We're thus glad that, this week, Tesla has acted publicly regarding its current GPL violations and has announced that they've taken their first steps toward compliance. While Tesla acknowledges that they still have more work to do, their recent actions show progress toward compliance and a commitment to getting all the way there.

Conservancy has been engaging with Tesla on its GPL compliance since June 2013, when we advised Tesla that we had received multiple reports of a GPL violation regarding Tesla's Model S. Customers who purchased Tesla's Model S received on-board system(s) that contained BusyBox and Linux, but did not receive any source code, nor an offer for the source. In parallel, we also asked other entities to advise Tesla about GPL compliance. We know that Tesla received useful GPL compliance advice from multiple organizations, in addition to us, over these years.

For our part, since we first contacted Tesla, we have been working with them collaboratively in various ways to convince their original upstream providers, NVIDIA and Parrot, to disclose complete, corresponding source (CCS) releases for all GPL'd binaries found in Tesla's Model S. During that time, Tesla privately provided Conservancy with multiple rounds of “CCS candidates“. (These are source code releases that are not yet complete and corresponding as required by the GPL.) Conservancy in turn reviewed their CCS candidates and provided technical feedback on how to improve the candidates to reach compliance. In this process, we provide detailed reports explaining how the candidate releases fall short of GPL's requirements. This part of the process is the longest, most difficult part of GPL enforcement. We often wish we could celebrate the triumph of moving from a no-source-or-offer violation to the next step of “incomplete sources provided”1. However, we also can't lose sight of the fact that compliance means meeting all GPL's requirements, so we don't convey false hopes with an incomplete release. We must ultimately remain focused on user freedom in our efforts.

This week, Tesla took a new and different approach. Tesla elected to publish its incomplete CCS candidates, on the online software development collaboration site, GitHub. While our preference is that companies provide adequate CCS immediately, we realize that this can be a challenging process and recognize that Tesla has struggled for years with upstreams to yield proper CCS. We believe Tesla's new approach also has merit, because it allows the entire community to discuss and contribute in public and collaboratively assist Tesla in complying with the GPL. In a case like this, engagement in the community may be an ideal way to transparently assure that compliance is achieved.

We look forward to facilitating Tesla with this new approach to compliance. Toward that end, Conservancy has created a public mailing list to discuss Tesla's source release (and, ideally, to also discuss other CCS candidates if other GPL violators choose to also take this approach.) The first post to this mailing list is our CCS candidate evaluation report 1, written by our Compliance Engineer, Denver Gingerich.

CCS reports have been the standard document of GPL enforcement since 1998. Conservancy has probably produced hundreds of such reports since we began. However, this marks the first time that circumstances have allowed us to share such a report with the public without violating our Principles. We're excited to do that, thanks to Tesla's willingness to engage everyone in their GPL compliance process.

We know many of you, particularly those Linux-savvy folks who bought Tesla vehicles, have reached high levels of frustration with the lengthy time this GPL compliance effort is taking. Nevertheless, this situation shows precisely why patience is essential for successful enforcement work; it gives us the opportunity to welcome violators to become contributors to the copyleft software community. Our community's history is filled with such success stories. To that end, we ask that everyone join us and our coalition in extending Tesla's time to reach full GPL compliance for Linux and BusyBox, not just for the 30 days provided by following GPLv3's termination provisions, but for at least another six months.

We welcome those interested in the CCS evaluation process to join the mailing list, as this marks one of the few opportunities to engage pubilcly in CCS evaluation. Additionally, anyone who holds copyrights in Linux may join our enforcement coalition of Linux Developers by writing to <linux-services@sfconservancy.org>


1 While Tesla partly corrected the violation yesterday by making some offers for source, the source provided is not complete, corresponding source with complete “scripts used to control compilation and installation of the executable”. Denver's email outlines the specific, current compliance failures.

Copyleft compliance misconception #1: Companies check their source builds before publishing

by Denver Gingerich on February 15, 2018

We often hear from people that are confused about why companies fail to meet their copyleft compliance obligations - it seems fairly straight-forward to do, so why don't they all do it? In its many years of experience attempting to help companies comply with the GPL and other copyleft licenses, Conservancy has seen first-hand how many of the expectations software users have about how a company would release source tend to not be met the majority of the time. This post is Conservancy's first in a series on these common misconceptions about copyleft compliance, which will hopefully provide some insight for people wondering why these expectations are seemingly seldom met.

Misconception #1: Companies check their source builds before publishing

If you use or develop free and open source software, you probably find it natural for software projects to make building and installing their software as easy as posssible (or at least to provide contact points in case it is not). This is because getting people to use or contribute to such projects depends on these projects being straight-forward to build and install, otherwise people would just use something else (since normally they would have little invested in a project they can't build or install).

As a result, when companies publish source code as a result of their obligation to comply with the copyleft licenses in the software they distribute (usually this is their primary motivation - in rare cases (so far as we see it) companies are motivated primarily by engaging with the free software community, which we naturally try to encourage as much as possible), they do not have the same incentives as you would normally expect of a project distributing free and open source software. Consequently, companies tend to spend most of their time ensuring that whatever product they're selling to you (be it a router, Blu-ray player, smartphone, etc.) performs the functions it's intended to perform and meeting their bare obligations when it's shipped. They don't spend very much time working on the build and installation experience for those who would like to modify the software running on it after they receive it.

Furthermore, determining which parts of the device's overall build and installation process a company considers to be confidential is often not done, or is done under pressure so close to release time that the company does not wish to try untangling the portions they consider confidential from the portions that they are required to release in order to fulfill their obligations under the copyleft licenses for the software they chose to use.

What we normally see as the outcome of this (in the hundreds of source releases we've evaluated) is that the source code companies provide is nowhere close to meeting the requirements of GPLv2 (which is the copyleft license we most often see being violated), which state that companies must provide "the complete corresponding machine-readable source code" for all the GPLv2-licensed software on the devices they distribute and that "The source code for a work means the preferred form of the work for making modifications to it [which includes] the scripts used to control compilation and installation of the executable."

There are a variety of reasons that a company's source release might fail to meet the above requirements. In many cases we find that the versions of the source packages they provide are nowhere close to the versions of the binaries they distribute. Or their source release is missing entire source packages - i.e. they distribute a binary for Copylefted Project A, but do not provide any source code for Copylefted Project A, even though they might include source for Copylefted Project B.

Even if the above issues are not present, most often we find that there are no scripts at all for installing the software on the device (either in machine- or human-readable form), and any scripts we might find for controlling compilation of the executable are little more than what the original maintainers of the source package provided (which normally means people outside the company shipping the device). As a result, the compilation does not succeed because any changes the company made to the original source package are not considered in the build instructions (the company likely got it to build at least once, in order to ship it on the device, but decided not to document or share that process in their source release). This is particularly frustrating to the people who report the violations to us, as they often want access to the source code to do something particular with the devices they own.

After seeing this pattern in dozens of different source releases from dozens of different companies, it is clear to us that companies do not normally check to see if the source they release can actually be built and installed. Rather than being motivated primarily by meeting the perceived legal requirements of copyleft licenses and thus releasing markedly incomplete source code, our hope is that more companies will start to see the primary motivation for source releases as a way of engaging with the free software community, from which correct build and installation instructions (and indeed fully compliant source releases!) will naturally follow. We've already seen community development projects like SamyGo and OpenWRT form around Samsung TVs and Linksys routers and we hope other companies will see the benefits and help build such communities right from the start.
