Unfortunately, this sort of problem is basically unsolvable for Linux (and other such "open" platforms). Either you get a proprietary blob that implements a protection scheme, or you simply don't get the functionality being promised.
Objecting to efforts to make the situation better for HTML5 experiences on other platforms because it won't work on Linux is, honestly, pretty selfish. It can't work on Linux, so you're basically saying since it can't work for you, it shouldn't work for anyone else too. And that's just dragging down the state of the web to the lowest common denominator.
