I can still play my brother's old PlayStation games on his OG PlayStation. They cannot be revoked arbitrarily, nor their music dropped or swapped out. This a feature, and we'd feel quite cheated if that happened. In fact we still go back to old games from time to time.
> Why carry water for billion companies?
All companies at a certain scale are billion dollar companies. Also, how much money a company has is unrelated to whether they violated consumer rights or not. But, tangentially, I do generally respect entities that fund creative endeavors moreso than I respect gamers who go online to bemoan how persecuted they are
Sony also keeps records, but good luck redownloading your PSP game. Or your PS3 game for that matter. But at least in that case, if you already have it downloaded, you can still play your game. Sony couldn't come down from above and turn your game into a rock.
The Crew for PS4 on the other hand. You can (probably?) still redownload that, but that doesn't actually do you any good. Ubisoft did come down from above and turn that into a rock (there is no good reason to make a single-player gamemode online-only).
