This has not been the case with Apple.
Pretty much any luxury brand has high product margins, but certainly not for lack of competition.
Or get it from a cafe, and value my time at around 2-3€ per cup
Too many usinesses can't live without access to iPhone users.
Of course, software sales have much higher margin of production cost (every copy but the first is free-to-make).
If Apple/iOS is a minority that means someone else must be a majority. Who, exactly, do you think should be the target of that balancing, and why?
That is why it isn't 30% after the first year. It is 15% for subscription based software starting year 2. As I pointed out earlier, Apple also eats credit card transaction costs (~2.5%) and the costs of collecting and paying sales tax in 50 states and 155 countries, app store personnel, servers, etc...
