Apple is already allowed to profit from their platform. A developer offering InappPurchase doesn’t use any apple services= apple lose the right to a commission.It’s not about payment solutions!
Apple’s commission is about profiting from the platform they built, iOS. What they have revealed now is that 3% of that cut is for payment processing- competitive with other offerings. 27% is not. If they have to offer alternative stores, they will subtract the cost of operating the App Store from the 27%.
Apple intends to profit from iOS, and those who develop for it using Apple’s infrastructure. Regulators may ban Apple from mandating that devs use Apple’s infrastructure (such as IAP or the App Store) but Apple will still enact a charge for whatever services it is allowed to provide. Regulators will have to fight Apple over each individual part of the 30%, and demand Apple allow alternatives for each bit. And if there is no good alternative (such as Xcode, notarization, etc.) then they will need to justify why Apple, singled out from all other companies, is not allowed to profit from the platform it built.
Xcode is provided for free.
Uploaded to AppStore costs 99$\year
Sale on store costs 15-30% cut of sales price
Using apples IAP connected to apples iTunes billing system costs 15-30% of sales price
APIs aren’t covered under copyright.
Developers aren’t using any IP that apple owns. Essentially undermining apple’s claim to revenue split, royalties(you can’t have a royalty on nothing)
And if apple continue it could in the worst case end up being forced to separate its business from the AppStore as separate businesses and use the The Digital Markets Act
