What Sony could do is patch restrictive DRM software into all their games that checks the hardware info and fails to boot if you’re on “an xbox”.
They’d definitely do that, they’ve already used what amounted to a Rootkit for DRM in the mid-2000s, so your idea wouldn’t even be the worst they’ve done lolol
Yea, if you update your game with new stuff that causes performance issues on older things, then just put up a warning about it and call it good
Sometimes these companies do way too much
