Re: Winds of freedom for graphic drivers!!!
Agreed. Whilst proprietary drivers might be "acceptable", they certainly aren't "better".
I'd stop defending a company you don't work for. NVIDIA and other companies use the IP claims as an excuse. The reason vendors want to close sources is to retain control on the direction and extent of development. It allows them to influence uptake of features they develop (by making alternatives inferior) and allows them to control "obsoleting" older hardware, forcing people to buy new hardware.
It's that simple. OSS drivers are consumer friendly and vendor unfriendly.
