Not seeing the big picture, are you?
... to continue to use non-standards compliant front ends. We'll be stuck with Flash/Air/Silverlight/Java forever - great plan EFF!
If DRM is put into the standard, we'll have a lot of black boxes that are not only the propietary crap packaged into one tidy black box, support will depend on whoever makes that black box. If the Big Hollywood Studios, or Netflix, or whatever deem that supporting Linux is too much of a hassle, we'll end up worse than what we currently have. At least Flash is supported in Linux (though Adobe does seem to be phasing that plugin out), and Java does have actual support in most OSen out there.
