Well one can argue wheter Cross Play is a good thing or not.
I would say it depends on the game.
As a mainly PC Gamer I don't mind crossplay in shooters.
Those are easy targets.
Maybe thats why Playstation executives didn't like the idea.
Having console gamers with their limited controls facing against highly skilled keyboard and mouse gamers.
On PC a player can even tweak the games configs, making more customizations, blending out vegetation in distance and so on to have an advantage in MP games. I've seen it all.
And lets not forget cheating issues.
So yeah while there are many games that wouldn't suffer so much from cross-play others would in my opinion.
