Public Support Makes All the Difference for GPL Compliance
by on January 9, 2020
In starting the new year, I am reminded of what we accomplished last year, but also of what we urgently need to get done this year. What I do at Conservancy is relatively unique, not just within Conservancy, but within software freedom non-profits as a whole. My primary focus is ensuring that organizations comply with the GPL so that people like you can continue to enjoy the freedom that the GPL and other copyleft licenses guarantee. Although it's a small part of what we do at Conservancy percentage-wise (partly due to funding constraints), GPL compliance and enforcement is crucial to the future of software freedom.
Your donations so far have allowed us to check numerous companies' source releases this year, each time getting us a bit closer to the goal of fully compliant releases of the GPLed software they use. While this is certainly important, it is frankly the bare minimum that we need to do in order to prevent the GPL from being treated as a permissive license that companies simply use to proprietarize all the code they use. We don't want to see your freedom taken away, and we need to keeping fighting to avoid that future.
We are at a turning point for software freedom. As our lives rely more and more on software embedded in the ever-expanding set of devices we use, it is more and more critical that we control the software they run. Companies need to see that not only is it straight-forward to comply with copyleft licenses, but that copyleft compliance is in fact a feature that their customers are specifically looking for (most companies do not comply with the GPL - we need both carrots and sticks to fix this). We have a project underway that we hope will solidify this in companies' minds, and with continued funding we plan to build and release substantial parts of it this year.
Persistent GPL enforcement has begun to change the software and hardware industry norms in our favour. However, we are at risk of losing all we have accomplished so far unless we are able to both continue our work in the fields that we are familiar with, but also, and even more importantly, to recognize and respond to new threats to our freedom as our digital world changes, demanding new software freedom licensing strategies and enforcement methods.
We often call on the community to help us with compliance work, but it is no exaggeration when I tell you that our ability to ensure your software freedom is a direct result of donations from individuals. The deadline for having your contributions to Conservancy doubled is next week and we have a ways to go to make our match challenge, so if you'd like to increase your donation or get your friends to support us, don't delay! You can find the full match details and donation info here.
Toward Copyleft Equality for All
by on January 6, 2020
I would not have imagined even two years ago that expansion of copyleft would become such an issue of interest in software freedom licensing. Historically and for good reason, addition of new forms of copyleft clauses has moved at a steady pace. The early 2000s brought network services clauses (such as that in the Affero GPL), which hinged primarily on requiring provision of source to network-remote users. Affero GPL implemented this via copyright-controlled permission of modification. These licenses began as experiments, and were not approved by some license certification authorities until many years later.
Even with the copyleft community's careful and considered growth, there have been surprising unintended consequences of copyleft licenses. The specific outcome of proprietary relicensing has spread widely and — for stronger copyleft licenses like Affero GPL — has become the more common usage of the license.
As the popularity of Open Source has grown, companies have searched for methods to combine traditional proprietary licensing business models with FOSS offerings. Proprietary relicensing, originally pioneered by MySQL AB (now part of Oracle by way of Sun), uses software freedom licenses to compel purchase of proprietary licenses for the same codebase. Companies accomplish this by ensuring they collect all copyright control of a particular codebase, thus being its sole licensor, and offer the FOSS licenses as a loss-leader (often zero-cost) product. Non-commercial users generally are ignored, and commercial users often operate in fear of captious interpretations of the copyleft license. The remedy for their fear is a purchase of a separate proprietary license for the same codebase from the provider. Proprietary relicensing seems to have been the first mixed FOSS/proprietary business model in history.
The toxicity of this business model has only become apparent in hindsight. Initially, companies engaging in this business model did so somewhat benignly — often offering proprietary licenses only to customers who sought to combine the product with other proprietary software, or as supplemental income along with other consulting businesses. This business model (for some codebases), however, became so lucrative that some companies eventually focused exclusively on it. As a result, aggressive copyleft license overreading and inappropriate, unprincipled enforcement typically came from such companies. For most, the business model likely reached its crescendo when MongoDB began using the Affero GPL for this purpose. I was personally told by large companies at the time (late 2000s into early 2010s) that they'd listed Affero GPL as “Never Allowed Here” specifically because of shake-downs from MongoDB.
Copyleft itself is not a moral philosophy; rather, copyleft is a strategy that software freedom activists constructed to advance a particular set of policy goals. Specifically, software copyleft was designed to ensure that all users received complete, corresponding source for all binaries, and that any modifications or improvements made anywhere in the chain of custody of the software were available in source form to downstream users. As orginially postulated, copyleft was a simple strategy to disarm proprietarization as an anti-software-freedom tactic.
The Corruption of Copyleft
Copyleft is a tool to achieve software freedom. Any tool can be fashioned into a weapon when wielded the wrong way. That's precisely what occurred with copyleft — and it happened early in copyleft's history, too. Before even the release of GPLv2, Aladdin Ghostscript used a copyleft via a proprietary relicensing model (which is sometimes confusingly called the “dual licensing” model). This business model initially presented as benign to software freedom activists; leaders declared the business model “barely legitimate”, when it rose to popularity through MySQL AB (later Sun, and later Oracle)'s proprietary relicensing of the MySQL codebase.
In theory, proprietary relicensors would only offer the proprietary license by popular demand to those who had some specific reason for wanting to proprietarize the codebase — a process that has been called “selling exceptions”. In practice, however, every company I'm aware of that sought to engage in “selling exceptions” eventually found a more aggressive and lucrative tack.
This problem became clear to me in mid-2003 when MySQL AB attempted to hire me as a consultant. I was financially in need of supplementary income so I seriously considered taking the work, but the initial conference call felt surreal and convinced me that MySQL AB was engaging in problematic behavior . Specifically, their goal was to develop scare tactics regarding the GPLv2. I never followed up, and I am glad I never made the error of accepting any job or consulting gig when companies (not just MySQL AB, but also Black Duck and others) attempted to recruit me to serve as part of their fear-tactics marketing departments.
Most proprietary relicensing businesses work as follows: a single codebase is produced by a for-profit company, which retains 100% control over all copyright in the software (either via an ©AA or a CLA). That codebase is offered as a gratis product to the marketplace, and the company invests substantial resources in marketing the software to users looking for FOSS solutions. The marketing department then engages in captious and unprincipled copyleft enforcement actions in an effort to “convert” those FOSS users into paying customers for proprietary licensing for the same codebase. (Occasionally, the company also offers additional proprietary add-ons, improvements, or security updates that are not available under the FOSS license — when used this way, the model is often specifically called “Open Core”.)
Why We Must End The Proprietary Relicensing Exploitation of Copyleft
This business model has a toxic effect on copyleft at every level. Users don't enjoy their software freedom under an assurance that a large community of contributors and users have all been bound to each other under the same, strong, and freedom-ensuring license. Instead, they dread the vendor finding a minor copyleft violation and blowing it out of proportion. The vendor offers no remedy (such as repairing the violation and promise of ongoing compliance) other than purchase of a proprietary license. Industry-wide. I have observed to my chagrin that the copyleft license that I helped create and once loved, the Affero GPL, was seen for a decade as inherently toxic because its most common use was by companies who engaged in these seedy practices. You've probably seen me and other software freedom activists speak out on this issue, in our ongoing efforts to clarify that the intent of the Affero GPL was not to create these sorts of corporate code silos that vendors constructed as copyleft-fueled traps for the unwary. Meanwhile, proprietary relicensing discourages contributions from a broad community, since any contributor must sign a CLA giving special powers to the vendor to continue the business model. Neither users nor co-developers benefit from copyleft protection.
The Onslaught of Unreasonable Copyleft
Meanwhile, and somewhat ironically, the success of Conservancy's and the FSF's efforts to counter this messaging about the Affero GPL has created an unintended consequence: efforts to draft even more restrictive software copyleft licenses that can more easily implement the proprietary relicensing business models. We have partially succeeded in convincing users that compliance with Affero GPL is straightforward, and in the backchannels we've aided users who were under attack from these proprietary relicensors like MongoDB. In response, these vendors have responded with a forceful political blow: their own efforts to redefine the future of copyleft, under the guise of advancing software freedom. MongoDB even cast itself as a “victim” against Amazon, because Amazon decided to reimplement their codebase from scratch (as proprietary software!) rather than use the AGPL'd version of MongoDB.
These efforts began in earnest late last year when (against the advice of the license steward) MongoDB forked the Affero GPL to create the SS Public License. I, with the support of Conservancy, rose in opposition of MongoDB's approach, pointing out that MongoDB would not itself agree to its own license (since MongoDB's CLA would free it from the SS Public License terms). If an entity does not gladly bind itself by its own copyleft license (for example, by accepting third-party contributions to its codebases under that license), we should not treat that entity as a legitimate license steward, nor treat that license as a legitimate FOSS license. We should not and cannot focus single-mindedly on interpretation of the formalistic definitions when we recommend FOSS licensing policy. The message of “technically it's a FOSS license, but don't use” is too complicated to be meaningful.
A Copyleft Clause To Restore Equality
My friend and colleague, Richard Fontana, and I are known for our very public and sometimes heated debates on all manner of software freedom policy. We don't always agree on key issues, but I greatly respect Fontana for his careful thought and his inventive solutions. Indeed, Fontana first formulated “inbound=outbound” into that simple phrasing to more easily explain how the lopsided rights and permissions exchanges through CLAs actually create bad FOSS policy like proprietary relicensing. In the copyleft-next project that Fontana began, he further proposed this innovative copyleft clause that could, when Incorporated in a copyleft license, prevent proprietary licensing before it even starts! The clause still needs work, but Fontana's basic idea is revolutionary for copyleft drafting. The essence in non-legalese is this: If you offer a license that isn't a copyleft license, the copyleft provisions collapse and the software is now available to all under a non-copyleft, hyper-permissive FOSS license.
This solution is ingenious in the way that copyleft itself was an ingenious way to use copyright to “reverse” the rights and ensure software freedom. This provision doesn't prohibit proprietary relicensing per se, but instead simply deflates the power of copyleft control when a copyright holder engages in proprietary relicensing activities.
Given the near ubiquity of proprietary relicensing and the promulgation of stricter copylefts by companies who seek to engage (or help their clients engage) in such business models, I've come to a stark policy conclusion: the community should reject any new copyleft license without a clause that deflates the power of proprietary relicensing. Not only can we incorporate such a clause into new licenses (such as copyleft-next), but Conservancy's Executive Director, Karen Sandler, came up with a basic approach to incorporating similar copyleft equality clauses into written exceptions for existing copyleft licenses, such as the Affero GPL. I have received authorization to spend some of my Conservancy time and the time of our lawyers on this endeavor, and we hope to publish more about it in the coming months.
We've finished the experiment. After thirty years of proprietary relicensing, beginning with Aladdin and culminating with MongoDB and their SS Public License, we now know that proprietary relicensing does not serve or extend software freedom, and in most cases has the opposite effect. We must now categorically reject it, and outright reject any new licenses that can be used for it.
Calling all Tesla owners: let's discuss the source code for the GPLed parts of your car!
by on October 30, 2019
It has been many years since we started working with Tesla to help them resolve their ongoing GPL violations. However, Tesla has still not provided the necessary source code for their cars (a benefit of ownership enshrined in the GPL, which Tesla chooses to use) and the incomplete versions of source they have released are more than 17 months old (at the time of this writing), despite new firmware being continuously delivered to Tesla vehicles. There have even been several updates within the past month. We know Tesla owners that care about software freedom are frustrated that they cannot exercise theirs.
We are looking for new ways to approach this issue. In particular, we are hoping to engage with interested Tesla owners to determine how we can work together and collectively improve the situation.
If you own a Tesla Model S, Model X, or Model 3, or know someone who does (especially in Canada, where I live) and would be interested in joining a discussion with Conservancy and other Tesla owners about this issue, please email us indicating your interest in the Tesla discussion. We'll get back to you in a day or two with details on how to join the conversation.
Please spread the word. Help us continue our work to bring meaningful software freedom to new classes of hardware, one manufacturer at a time.
When companies use the GPL against each other, our community loses
by on October 2, 2019
Our Executive Director, Karen Sandler, has warned for years about the dangers of lawsuits between two for-profit companies engaged in a legal dispute in which the GPL is tangentially featured. Unlike Conservancy, companies don't use legal action as the last resort, and they don't select their cases, as we do, focused on what's best for the software freedom of users. Nevertheless, these cases happen, and the GPL gets caught in the crossfire. With the assistance of our legal counsel, Pam Chestek, Conservancy has been carefully following the case of Ubiquiti Networks, Inc. v. Cambium Networks, Inc.
Cambium and Ubiquiti have been engaged in this lawsuit with each other for a little over a year now. Ubiquiti sued Cambium, claiming that Cambium violated RICO, the Computer Fraud and Abuse Act, the Digitial Millennium Copyright Act, and the Copyright Act, along with other causes of action. Cambium responded alleging that the Ubiquiti products included code under the GNU General Public Licenses and Cambium's own use of the portions of the Ubiquiti code subject to the GPL would not be an infringement. The case is still in very early stages.
As experts in GPL compliance, we carefully investigated the situation with each company. Ubiquiti was already known to us as we had received independent GPL violation reports from the public regarding their behavior. (The suit itself brought Cambium to our attention.) We have found that neither company complies properly with the GPL. Specifically, in our analysis of the facts, we have found that both Cambium and Ubiquiti fail to provide any source code for their respective routers and access points, even when we repeatedly asked over the course of several weeks, starting more than 30 days ago. This is not an issue of incomplete source or partial source; we have received no source code at all to review. Furthermore, even if we do receive some source code, the firmware images currently available indicate that there may be additional serious, overarching GPL compliance problems that are not easily resolved.
As for-profit GPL violators, these companies financially benefit from GPL non-compliance by for-profit companies. Their litigation around GPL is a distraction from the bigger issue of companies' repeated violations of the GPL. We lament the irony that two companies have begun a fight regarding GPL compliance (and deployed immense legal resources in the process), yet neither complies with GPL's most basic provisions. Because of this, it's unlikely this suit will yield GPL compliance by either party, and makes the suit another example of how for-profit legal disputes inevitably fail to prioritize the software freedom of users. In essence, we believe their dispute is not about empowering their users with the ability to augment their devices by improving and upgrading the software on them, but rather is about who is able to keep more of their code proprietary.
Conservancy will not stand by while this occurs. As such, we have today opened (at this point, non-litigation) GPL enforcement actions against both companies. We are informing the public of this situation in this blog post, since we gave both companies the industry-accepted standard amount of time to comply, and since the two companies have already made their violations public through the lawsuit filings. We call on both companies to immediately comply with the requirements of Linux's license, GPLv2.
