Others will probably rate down your post, but it was a good analogy for the post before yours. Nobody gives (or should give) a fuck if they can't play for an hour because the internet is out. That is not the problem with this service. The problem that it probably gives your an inferior gaming experience.
The only access concerns I really have are way down the line, when a company goes under like Atari did and who knows what happens to their DRM/streaming servers. Also corporate control at all times like that can lead to censorship or editing that you can't do anything about. This is more a concern with movies for me, but with games changing music or or whatever sometimes it's also a concern with them as well.
