But of course the real reason they would love to prevent anyone from tampering with the game is so they can sell more single player cheats such as experience booster packs.
I would be more interested to hear about games such as god of war or horizon zero dawn, which have no online play at all, used anti-cheat.
Banning on single player would be silly. But GTAO is another story. It's designed as a cash farm. You have to grind missions, buy shark cards or use cheats. So as I understand they will ban anyone if they detect it's using mods/cheats. But GTA anti-cheat systems are weak and sessions are P2P or at least were.
I don't personally play either game, but from what I've come across on the subject over the years, publishers seem to be a lot less difficult about it today compared to a few years ago. I recall reading about them denying a ban was due to mod use when they were wrong, being ridiculously vague about what modding was and what wasn't allowed, refusing to fully restore a player's character even after a ban was rescinded, etc.
