Ah, this is what is scientifically known as a 'rabbit hole', isn't it ? It has many exits, most of them where you don't expect.
I have used computers since 1978, and have watched - and used - every single next step of integration in office, industrial, gaming, utility, tooling and every other variation on implementation you care to imagine. Or not.
There is a recurring pattern. A problem presents itself, for which a singular solution is devised (let's say, for the sake of discussion, someone would like to play a 'sound file'). Pretty soon, someone is going to come along saying 'this is great, and if we add that we could do that too (let's say store several sound files on one computer). Then someone will want to search them. Then someone will want to view a video. Then someone remarks 'wouldn't it be nice if I have a sound clip I could find the associated videoclip'. After which, if you could play a clip, maybe you could play a movie. I leave the rest to your imagination. As time moves on, more and more extras, expansions, new possibilities, novelties etc. get bolted on. Then someone says they have more than one computer. And it starts over. Of course, the purveyors of this multimedia bonanza explicitly DO NOT want things to be all access. The number of viewers is limited, their budgets are limited, so they want lock-in. All of them. Untill someone finds yet another niche they think they can monetize, and think up yet another 'unique' service. And so it goes on.
It happened with itunes, untill even Apple themselves realized they couldn't make it work properly anymore, and they cut it up. And this is a company which controls its own ecosystem. Imagine dealing with Linux, where every Tom, Dick and Harry their own spin on the underlying gears as well. And every time one of the providers changes something, you have to fiddle with the entire mechanics. Netflix now works again, but Amazon, Tidal, Qubuz and the local digital providers are broken.
I think eventually there's going to be an MC music, and MC Movies, an MC books, and MC stamps for all I know. Unless everyone decides they're all going to go back to 3 national broadcasting channels.
