It would be interesting to hear how she wants to make money on Apple platform by not following the rules and not paying fees for access to Apple user base. It seems zoomers live in alternative version of Universe where everyone is owing them something.
"Paying fees for access to Apple's user base" is called an "illegal tie-in sale" in antitrust law.[1]
She, the fanhouse app owner, only takes 10% from the content creators
It doesn’t really matter. Apple takes 30% since rules are for all. You can do your business on Android in 3rd party store or without store and don’t pay any fees. But Android users are poor by statistics and no one is using sideloading or 3rd part stores in US. That’s why she hates Apple - they built successful and platform by investing billions and now someone wants to exploit it for free.
