There is room for 3rd party app stores. Epic will argue that Apple does an absolutely ghastly terrible job of curating the Apple app store, as Apple really has little incentive not to suck completely. The EU court will agree. Apple will spend a year or two saying “it can’t be done”, then issue a signing certificate to Epic.
> There is room for 3rd party app stores. The "Apple Tax" pays for the maintenance of the Apple ecosystem. Epic wants access to this amazing ecosystem, but resents having to help pay to support it. Either "third party" app stores will also pay to support this ecosystem, in which case Epic will be paying the same amount either way; or they'll fail to support the ecosystem, in which case Apple will be forced to turn to…
how did you work out that the amount apple gets paid (30%) is the "correct" amount? The only way to find out is via competition.
