Yeah maybe not, it's mostly just Nintendo, I wouldn't put it behind Microsoft to do something similar, though they haven't tried anything yet, and also don't really have any console exclusives anymore (that they care about, most of them are forgotten on Xbox 360).
Sony shouldn't sue anyone emulating PS4/5 stuff. AFAIK, PC is the king of modding.
