Ah, good old NIH syndrome. We totally can't use that Wheel thing because those jerks over there invented it! Let's stick with the Square even though it's technically inferior!
Nothing is preventing those other vendors from implementing VDPAU drivers.
Re Flash GL accel - last I checked this had to be forced on for everyone running FOSS drivers. Not to mention GL accel is on older cards worse than x11, not to even mention xv.
If nv controls the API then you might as well say intel controls VA-API (you know the company that has been getting hammered on in court with anticompetitive practices). Nvidia made it painfully clear since the very beginning that vendors are free to implement their own vdpau support but it seems some people like to append their own baseless conclusions about it's license.
Hi guys, the follow-up post mentioned in that blog entry is now available, and explains the thought process better, and answers the questions posed in the previous blog's comments, plus some other common questions about Flash, CPU's, and GPU's.

Yeah, why did NVIDIA create VDPAU when good old VAAPI already existed?
I don't necessarily see anything wrong with companies choosing to implement vdpau acceleration in their drivers, it's certainly possible. But the real question is why should they? VAAPI already supports Intel + ATI (sort of) + Nvidia, so it doesn't make much sense from their perspective to suddenly change their development to focus on a different API that nvidia is pushing for.
I mean, sure it's a little buggier for now, but if they all suddenly switched to vdpau their vdpau implementations would all be even buggier. Hopefully they'll get all the bugs ironed out soon.
VA-API was an a slow train to nowhere, was featureless ( and somewhat still is lagging ) and really was only useful at the time on the GMA500 (and we all know how well it's supported). Nvidia got the ball rolling and was extremely well received and adopted for various projects.
