The difference is everyone CAN install a bad anti-cheat, or decide to not do it.

But if people who bought the game suddenly CAN'T legally play it anymore, because PSN doesn't allow accounts in their country, they don't even have a choice.

Selling the game in those regions in the first place was deeply wrong, but then taking away the ability to play AFTER they sold it to people, that's a bridge too far.

And we're not just talking about most of Africa (not that that would be less bad), we're also talking about countries like Latvia, Estonia and Lithuania, those are EU members, how is there no PSN available there?
