Is that right though? Is the economics as simplistic as that? Could it be that Apple can now bring down iPhone device prices while hitting the revenue targets they have in mind offset from services, effective benefiting iPhone SE 2020 consumers? Could it be that the cost of running the store, marketing and distribution and properly reviewing all the free apps that I actually use is subsidized by the minority of apps that are paid or have in app purchases? To say that the user is burdened by the entire 30% directly is quite an overreach. How do we know the developers won’t pocket the additional margin and keep prices at the current rate? (my bet is this, actually).
For me personally who almost never used a paid app, I can assure you that the 30% is not paid by me. I may have even benefited through iPhones cheaper than hypothetical price that Apple has to sell them without AppStore revenue potential. I certainly benefited by AppStore vetting shitty apps.
This is a business model choice and banning it is like saying Google Drive is not supposed to charge paid users more to subsidize free quotas.
Are you fine with paying Apple 30% of the cost of any application that you buy? It's not the developers that are paying this cost -- this is what you are paying to Apple for each app. That $25 app is costing you $7.50 that goes straight to Apple. All that money adds up fast.
Even if you are good with that, I think you imagine that a lot of users -- even those who might be happy with other aspects of the Apple ecosystem -- might not be happy with a 30% tax on all purchases made on their thousand dollar device. Apple even mandates that you're not allowed to know inside of an app about cheaper ways to pay.
