In my opinion what Apple is doing to Epic and others who are worth millions/billions is a form of legalised racketeering. Apple knows the games produced by Epic are extremely popular hence they look for a way to profit from Epic and they do so by forcing Epic to use Apple's own payment system which incurs a 30% charge everytime an Epic user makes an in-app purchase for one of it's games.
They force *everyone* to use Apple’s payment system, regardless of popularity, but only if the developer wants to use Apple’s intellectual property and do transactions in the app.
If you don’t want to do transactions in the app, you are free to do so outside the App Store ecosystem, and apple will still graciously allow you to use it’s intellectual property for a $99/year flat fee.
Not exactly racketeering. (By the way “legalized racketeering” is an oxymoron.)
