Its actually very simple: Some companies like Nvidia, they understand that Linux will dominate shortly, and they have decided to gain full access to all the goods without giving anything back. Thanks but no thanks. if you want all the GPL yours, then open your driver. That doesn't mean to open everything, just the driver and the things untillOGL3.3, then use OGL4-4.3 like closed extensions for the open driver. Those close extensions they will only have graphics extensions (compilers, programs for the synthesizer, FX), and no driver functionality like memory management, that must be open. Also this open (and if you want unified driver), you can use it for all operating systems.
No announcement yet.
