If you cared enough, I do wonder if you could win in court, if you pirated a movie that you purchased on the PS5, but Sony removed. It would cost you an ungodly amount of money to defend yourself against Sony, and I don't know the exact words of the "license", but it seems like a reasonable action to take.

I wonder if their use of a "buy" button would potentially weaken their case regardless of the language they put in the EULA.

It'd be a case where the spirit of the law clashes with the letter of the law.

Sony's lawyers would argue about how things are, while your defense has to argue about how things should be.

Which way it goes likely depends on how sympathetic the judge is rather than actual arguments being made.
