"Don't get too attached to your apple account. It belongs to Apple, not you."
This also applies to games you’ve bought you’ve bought digitally as well, *especially* if it requires an internet connection to work, even if it’s a single-player game (I’m looking at you, Elite Dangerous!)
IIRC, you’ve basically bought a license to play a game, you don’t own it in the traditional sense… A license that can be revoked on the whim of the company you ‘bought’ it from
One exception might be games you’ve purchased from someplace like GOG.com, which IIRC are DRM-free
