Re: Are you sure that this "community of developers" exists?
A complete GPU software stack that doesn't taint the kernel is worth having, whatever it takes.
By "complete" I mean a VDPAU equivalent, the same crypto-mining performance as the closed source driver, etc etc. (hopefully Intel won't even release a closed source driver... there's no point for a hardware company to stick to closed source).
The old Intel 3D hardware (from like 15 years ago) was great as far as GPL driver support - 3D screen savers worked out of the box without kernel tainting.
ATI (AMD?) tried and failed to get a proper open source GPU driver, and NVIDIA isn't even pretending to care about the GPL. Intel has always been better about this -- hopefully their new GPU line will finally make kernel-taint-free GPUs a reality.
