You do realize that Sony has been selling games in those countries for years? God of war isn’t delisted, neither are Horizon games, neither are Spiderman games. The upcoming Ghost of Tsushima isn’t delisted either (edit: seems like it is getting delisted).
The delisting isn’t related to Sony selling the game. If it’s related to anything it’s related to the PSN requirement. And I think people are rightfully complaining because there no need to have PSN in those games. It’s a stupid push by Sony that is also forcing them to delist their games.
