People usually mix up things: The clear clause in their ToS is about selling Steam keys. A dev on Steam can generate Steam keys and sell them wherever they want, and Steam does not take a cut on those. For those, there is an explicit clause that says that you need to match the pricing on Steam.

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.
