Arrowhead also knowingly sold a game in markets where it wouldn’t be possible to play the game, even at launch with the restrictions in place you could buy the game in these markets. Steam also allowed these games to be sold in markets where they knew the restrictions wouldn’t allow them to play the game.
They fucked up and are now trying to deflect blame from themselves, yeah Sony is shitty, but arrowhead and steam both saw dollar bills and tried taking them.
Edit, if anything, Sony can turn this around that Arrowhead and Steam strong armed their way out of the contract requirements. Steam and arrowhead should take the fall and costs in this one if that’s the case.
