Actually, Apple Store and Google Play (and Steam, yeah) are the same: they are monopolistic platform, either formally (Apple) or de facto (Google). A bit like IE browser in Windows in the 90's I think that each editor can still provide an App Store, with specific price model for editor/users, and have to allow competition (with different features... for example, less curation) by providing THE SAME access for the user. For example, every app store must include other main app store. Right now, if you want to use F-Droid, you cant do it as smoothly as using Google Play because it's not on Google Play (but Amazon apps are I think).
