Sony was never on our side.
E.G. Warframe is fully cross platform. You have an icon showing beside the player name if they are on the same platform as you, or a generic one if they aren't.
When the system launched, it showed unique icons per platform. Sony demanded that be changed because of the incredibly petty reasoning that if an xbox player beat a PS one in pvp
No, I played when that happened.
They launched it with icons for nintendo switch, xbox, PC and playstation.
Within a week they had to hotfix to the generic icons for stated reason because "Sony was worried about the meme potential of an xbox player beating a PS player in PVP." That was stated as the reason in one of their weekly livestreams.
