It's already a competitive landscape. If you feel Apple is unfairly charging you extra for something, then you have a myriad number of Android and other phones to choose from.
On the other hand, if Apple's model allows them to better compete with others and create a superior product that people want ... well then, it's ridiculous to mandate they should do business a different way.
their business business model allows them to compete because they're rent seeking by grazing off developers and apps that dont want or need their app store, payment processor, etc.
Wow who knew rent seeking was massively profitable, huge surprise!
