I don't like insulting people but - we don't care about public opinion, idiot. The public's opinion of whether or not running Linux is useful, productive or troublesome - doesn't matter. The majority's opinion doesn't matter here. We run GNU/Linux systems because we want to. We use free and open source software because we want to. Because we trust it more than closed source software. So we can tinker with it. Experiment away. To me there's so much freedom to experiment and learn just like I used to do when I was young - opening up radios or toys to see how they worked. Any computer science student or indeed any scientist can see the value of open source software - we can learn so much and we are free to share what we learn and create. We don't have to use restrictive licenses. If all we had were closed source systems like Windows or MacOSX or countless other ones, then computer science would not be able to progress the way it has so far. It's because people had the freedom to experiment with their systems the way they wanted to - without that kind of freedom none of the current "tech giants" would have existed.
Also, there's no such thing as content providers supporting systems - that's bullshit. All they provide is content - video and audio files encoded in certain formats. And VLC, ffmpeg can play a large majority of those formats.
Canonical doesn't care about your opinion on public opinion. They want a larger market share. If that means leaving you behind while getting another 10 users so be it. See, most people aren't as fanatical as you are, so they don't really care whether it contains DRM or not, or if parts aren't open source and all that. For you that is a big no no. For them the issue doesn't exist. They will choose what looks prettier. They will choose what plays their games. Those are the people Canonical is going for. As I've said, your opinion doesn't matter. Canonical's does.
We've established we hate DRM, OK. But the hard fact is, if we want Linux to advance; we need some form of DRM so companies can feel safe.
You don't need to bow to old media. It forsakes the foundations of FOSS by putting your content behind an obfuscated veil, the same way closed source software is a black box. Any DRM solution would have to be proprietary because if it were open sourced it would take minutes for someone to reverse engineer it and output unencumbered media.
