There are no wholesale prices for digital goods so they get tacked on as fees. All Apple is really doing is asking developers to give their customers an all-in price that they’ll display. You as a developer are free to raise your prices 30% on iOS, and many in fact do.
Every segment of every market does not need to be relentlessly competitive. Apple’s App Store rules are obvious, and if you don’t like them, you’re free not to develop for their platform (which itself is the product they sell to their consumers; not your app and of which the iPhone is only one component).
You are not entitled to be profitable any way you want; you have to find a niche in the market that’s profitable and if you can’t make money on iOS, the market solution is to just do something else. Countries — especially relatively small ones — that try to legislate around this are just as likely to be seen as more trouble for Apple than they’re worth to have an official presence in.
