Funny how some of the largest sites on the internet can base their entire business model on stolen pictorial content - completely with stripping off the identifying information of the original artists - and nobody at the W3C bats an eye.
But the moment the MPAA muscles their way into the debate, suddenly we're all about DRM.
If you want DRM, you use a plug-in or a separate application. There's no reason that an app like Netflix or whatever can't use pure-HTML for everything but the video-stream and use a plug-in based object for the stream.
Keep HTML free.
