I started hacking on Linux without any consideration for software licensing, I did it more out of pure joy out of getting a kick out of seeing hardware work which didn't before and collaborating with an amazing set of folks. Through my years on working on Linux though I've somehow stumbled on the front lines of licensing debacles both due to reverse engineering, copyright infringement claims, and later patent considerations. The only way I can explain why I kept working on things despite its debacles is that perhaps most people give up and I guess I just don't. Its been years now since working in the community, and in fact for a while even went on a hippy 'FreeBSD / Linux lets work together kumbaya!' with real technical solutions in place (part I, part II) -- on this post I'd like to provide some background and explain why I now fully support the GPL on Linux, believe its critical to enforce GPL on Linux and would like to declare I've given up on working on permissive licensed drivers on Linux and explain why. I write this to also explain in details why I fully support Christoph Hellwig's lawsuit against VMware filed today.
I've gone into details before about how I first got involved with hacking on Linux just to get my damn wifi to work, later jumped onto the MadWifi project and so began the 'ath5k wars'. Later as we put out the ath9k device driver I also engaged with Adrian Chadd from the FreeBSD camp quite a bit, eventually we ended up becoming coworkers and did our best on ending proprietary drivers for good by working together somehow. To prefix this I had called out to my Linux peers that we should consider simply localizing the GPL and look to work and engage collaboratively with the BSD camp. To this day I stand behind the technical ideas we put out together to share drivers for both BSD and Linux -- in the end the pitfalls however were what really set this effort back. I'll summarize them as follows:
- Software teams at companies who do care about proprietary and permissively licensed solutions tend to be super sloppy and in no way motivated to do much work
- Compared to the size of the amount of Linux developers the BSD camp stood no chance to help to keep up with what we were doing or putting out
- Given the above issues the real folks who stand to gain from a joint venture between BSD and Linux folks working together on device drivers are simply the proprietary vendors selling proprietary solutions
- Patents are a wild card, and best we have them on our side
- Proprietary vendors with patent interests will play their cards carefully and you are at their mercy
It seems VMware has done nothing in any way like the work I did to help with the use of permissive licensed drivers on Linux, which would likely be the minimum expected for some coexistence even with proprietary platforms without raising any eyebrows. Trust me, it was not easy work and just above I've declared I've given up on that and consider it pointless. Despite the best efforts by Conservancy to try to ask nicely to address the problem VMware has decided to opt out and play their cards. It seems VMware is trying to cut corners and reap benefits from our ecosystem on Linux in broad daylight. That's a bloody shame. Best of luck to Christoph, I fully support him on this lawsuit against VMware, if you feel the same I would like to encourage you to donate to Conservancy to support the VMware lawsuit, if you are a Linux kernel developer and share your sentiments consider joining the loose knit set of kernel developers under Conservancy wishing to seek GPL compliance on Linux, you can email email@example.com for further information.
