Sony still will they haven’t fully reversed the decision yet. The game is still delisted in 177 countries.

"Nearly"? They did not reverse anything. Game is still delisted in the countries that have no PSN access. Basically: "All the peope, who are not allowed to own a PSN account, you don't have to link your PSN account, don't worry. Still can't play the game tho, it's not sold in your country!" :')
