So to summarize:
You can create your own app store, but Apple controls it, and it will cost you.
You can create your own app store, but only you can publish to it.
You can use your own payment method, but Apple must be allowed to collect data and a large fee from every payment.
You can distribute apps that Apple approved in your app store, but you have to give Apple the data and pay per install.
Not even Google is close to that amount of data collection and greed...
