While I agree it is pretty cool, I think they probably did that to avoid a class action lawsuit.
But that does also beg the question, if we do eventually regulate this better, do you own streamed products? IE with Google stadia (and I think Amazon Luna) you buy a game but the game data is streamed to your device. If they shut the service down (like Stadia did) then what happens to your game collection?
It's a hypothetical, but interesting to think about nonetheless
