Sorry, it's 86% and 14% in Linux 4.11. It's literally in the link I posted. He gave a talk a few years ago at Linaro IIRC where he said "80% and 20%" as approximates but it seems like it's closer to 85% and 15%.

Companies which pay their developers to work for Linux want to exercise their copyrights. It wouldn't make sense for them to conceal developers they are paying to work on Linux. I would argue more people who are listed as "from company X" are working outside of their work but have to declare their company ties due to IP worries.

Well, it's actually a bit more far-reaching than that. Most companies also claim that work directly related to your job (even not on "company time") is still owned by them (which you can assume means that's what they're paying you for). Maybe that's not the case in Hungary, but that is the case in America (and Australia where I am).
> if you took the money out of the picture, our work would still continue to live on as it has for the previous 16 years. that is absolutely not true for upstream linux development
I mean, Linux kernel development worked in this way for the first several years when it started. It doesn't really make sense to make authoritative statements about what is and is not possible in hypotheticals. Both Linux and grsecurity were developed for some time without direct income sources from most contributors.
All of the being said, I'm not sure why any of this is relevant. To me the statement "we are 100% unpaid for grsecurity R&D" sounds more like a semantic game than an earnest statement, given that you definitely are paid for grsecurity (whether it says R&D on the invoice is semantics IMO).
But w/e. You can pretend that you aren't paid for your work to seem more righteous. You don't get any sympathy points from me though.
