I don't even think the issue is the crossplay- if sony doesn't want Xbox/Switch players joining up with PS4 players, whatever. But the fact that third party accounts can't be used freely (just because they were once linked with PSN) is the travesty. This is where bounds are being overstepped, because how the hell can they dictate how a 3rd party account works on another platform. And why be cool with PC/mobile, but hostile with Xbox/Switch (because of console war nonsense, of course). But while they probably *could* get away with it if MS and Nintendo were equally isolationist, they are not, so as odd man out, they are the bad guy here.
