The switching cost between launchers on PC is negligible, compared to phones where it's a massive undertaking. That said, in the context of user freedoms I think it's fair to not support Epic (in part, for their actions towards exclusive games) at the same time as supporting Epic (in part, for their actions on mobile platforms).
I don't think it is. While I may agree with the goal of open platforms, I don't for one moment believe that Epic cares at all about that goal and I do not believe their method of intentionally violating TOS and using propaganda to direct a raging horde of children at Apple is the right way to go about it.
