AFAIK Microsoft users can install software not using Microsoft store, however it is called.

Steam is not even controlling PCs as their fief so they cannot do this even if they would want to do it.
I figured it was likely unenforceable if a studio simply released a "steam edition" or whatever artificial version differentiation, but at the same time they can always refuse to do business with you for any reason (or no reason even). So at that point the clause feels like them making a blatant threat.
For just selling the game elsewhere, there is no such clause, and there are games that e.g. are cheaper on Epic and explicitly say that's because Epic takes lower fees. But there are also devs claiming that Valve pressured them in private to not do that, and that's what the lawsuit is about.
