That could be one reason, at least in a game such as MultiVersus with different IPs being used.
But they still lock down servers to their own shit when they own it all anyway and it’s because they also sell you crap to have in the game. If you had your own server, you could just give yourself the stuff they sell since all those things are still in the game somewhere and the only barrier between you and the content is their servers checking to see if you paid for them.
