You don't get it. HTML5 doesn't limit the use of closed, DRM'ed video. Moreover, the W3C is contemplating about an API in the HTML5 standard which can be used by third parties to implement their custom DRM. In both cases you'd need plug-ins for your browser to be able to see the video.

The chance that netflix will stream their media in open, DRM free standards are null. The chance that you can view netflix on your N9 is zero.

While the music industry has (partially) improved things, the motion picture industry still hasn't. It ties people to closed software, and for some reason people keep willfully or ignorantly paying for their own shackles.

Also, don't be misguided by HTML5 in general. Imho, the hole concept is "meh" at best.
