This whole debacle is unreal (pun intended?). I don’t think they’ll be able to enforce this the way they hope to. For example they want to be paid for unity games in subscription services, like xbox gamepass. Meanwhile M$ lawyers are rubbing their hands together in anticipation.

They’re going to (already have) damaged their reputation beyond repair. This isn’t typical consumer strong arm tactics. Their clients are businesses who already have alternatives. If one of my vendors abruptly changed our agreement like this, there’s no question I’d quietly phase them out ASAP.
