Remember the nvidia fallback patch? Pure political bullshit. Why hasn't vdpau been adopted even though it's by far the most complete and mature solution out there? Again more political bullshit. Or how about the time when they removed kernel code that they thought only would break the nvidia drivers? Only after did they find out that some oss projects did indeed use the same code (vbox in this case) did they temporarily put it back in to give time for the vbox to get their code up to snuff. Then there is the whole radeon vs radeonhd crap too.
