If you have a service that does not require an app, but the app is an additional convenience for your customers, why should Apple be entitled to 30% of everything? That is an extremely common scenario.
Because Apple wants it and they are one leg of the international duopoly of mobile OSes. And most small apps aren't important or differentiated enough for people to change platforms over.
This really needs concerted action on part of 5-6 big apps, such as Netflix, Facebook etc. Anything short of that, and Apple is going to keep eating their lunch like a school bully.
IMO it requires government regulation since the app stores function as virtual "natural monopolies" (natural monopolies are regional monopolies created by the nature of the product or service you provide). Natural monopolies are most definitely regulated by sane governments.
