So it doesn’t break down at all then, as the ‘rent’ is the dev fee, and $99 is not, in fact $0 as you’re trying to infer. If it’s not enough, that’s only apples fault.
Well, whilst that’s true, Apple is in no uncertain terms under full control of what can or can’t happen on iOS. So whilst they don’t have a monopoly on mobile OS’, they do on iOS. Now - under general conditions that’s a laughable statement. But this is not general conditions, there are billions of iOS devices. That’s where the problem lies, and that’s why the term gate keeper is used and not monopoly.
