Warframe, regardless of what you think of Digital Extremes, had cross platform play pushed last year out, more recently cross platform save too. Both worked out of the gate when launched, they did their homework.
At its inception, each platform had its own little icon beside the player name to indicate what device they were on.
Sony took a look at the system and apparently freaked out that there was the potential of a PS player losing a PvP match to an Xbox or Switch player and demanded via legal threats that it be changed immediately.
MS didn't seem to care and I think Nintendo was just amazed a half decent looking game with as many mechanics as Warframe can run on the Switch.
So now, players can see who is on their platform, and a universal icon if they aren't.
This is the case with every cross-platform game I've played on PS. PS logo for PS players, a generic icon for everybody else. Makes it really frustrating in crossplay games when I have to ask myself "Did I somehow get placed into a M&K lobby, or is this guy just a Xim cheater?"
Unfortunately it was in one of their live streams, and they do 2-4 hours a week of that. I'm not digging through several hours of video content for that.
All suits are losers who bend the knee to money. Bigger corps are like a bigger money pot to their twisted brains. OFC they'd bend the knee to Sony, a world renound brand name.
