Apple was the easier target, since Google allowed sideloading that could get whatever Epic wanted installed. They've gone after Google too of course - they want to remove all rules so they don't have to convince Android users to sideload.
They have even tried (though it was shot down in the decision today) to force Apple to let them install their own app store. So not only do they want to prevent Apple from collecting a penny from people playing Epic games, Epic wants to create its own app store - and would likely try to charge that same 30% they think Apple/Google shouldn't be permitted to as they would claim "our app store isn't a monopoly like theirs so we should be able to operate by whatever rules we want!"
Biting the hand that feeds IT
