At least, so far as Amazon is concerned:
This is no dubious speculation by tin-hatters. This is a legal argument Amazon made in open court. Digital belongs to the platform you watch it on. The purveyors of the content are the actual owners, and always will be. If you want to *own* perpetual viewing rights, you need to buy a physical copy.
This is just like Facebook, Twitter, or any other all-digital interaction. It’s their circus, and you’re just one of the monkeys. They will change, alter, undo any part of anything that happens in their circus, at any time, and you will have no recourse other than to leave the circus behind.
The concentration of digital activity into a small handful of web sites has given them a functional monopoly. They are going to act like monopolists, and already are. Supporting the decentralization of the Matrix is the only way forward.
