I'm not sure if Epic requires you to use their payment processor for IAPs, but even if they do it's not hypocritical in the slightest. The Epic Store isn't the only realistic way to sell a game/app/whatever on PC. That's the issue here - not that the store takes a cut, but that if you don't like the cut you have absolutely no way to try and go with an alternative.

If I don't like the cut Epic takes in their store I can go with Steam. Or gog.com. Or itch.io. Or sell things myself on my own website. If I don't like the cut Apple takes in their store on iOS I can go with... nothing.
