PlayStation Wants To Prove In Court That You Don't Own Your Digital Games

granted limited access to software that can be revoked at any moment.

If it is that, then it may not be called a purchase. Simple.

It should be called renting (or something similar). But then, that would likely mean an expectation of a lower price tag and they wouldn’t want that. Who would rent a game for $80? Even if the rental is a decade or longer. Probably people out there that would and currently do this.

It should just be called License. Put that there instead of the buy button. And clearly visible the minimum expiration date for the license. Reserve the buy button for actual perpetual licenses where not having access to the licensed good is a breach of contract good for money back.

Licenses are a copyright concept, but this isn’t a copyright issue. You’re buying a copy of a game, and you should own the copy after the purchase (which of course, means the company who sold it to you shouldn’t be able to revoke your access at will). That’s the part that sony is apparently not willing to do. But copyright-wise, it would be a license either way, so I don’t think it’s a good idea to confuse people with only tangentially related concepts here.
