The current "defense" seems to be that all those games are just to bait PC gamers to buy a PS5 to get the sequels. So I guess the only barrier left is day and date releases between PC and Playstation.I'm not interested in the Spiderman games, but on a meta-level I find the whole thing very entertaining.
It seems like every time Playstation superfans come up with a new reasoning on why specific games will never or not in some specified timeframe get released on PC, there's an announcement a few months later of exactly that happening.
