Apple's 30% tax does, like real taxes at least get you something in return: bug testing, hosting, API security, SDK support, a distribution channel with hundreds of millions of potential customers and if your app is something of a success, marketing. Apple has server space from Amazon to pay for and wages of staff.

The only way Apple will (sadly) ever offer alternate payment methods is by opening up iOS to sideloading and basically saying to devs if you want to go it alone and entirely self-fund all the services we provide, go ahead.

The Epic trial was a ruse to begin with. Mobile made up less than 5% of Fortnite revenue and PlayStation 60%+. Epic only went after Apple as they were the biggest fish and the free publicity the tech press provided them for months on end. They weren't about to take Sony to town and bite the hand that feeds them.
