In theory that sounds like an alternative but in practice it’s not. Developers are not going to create two versions of the same app, one for the App Store and one for an Alt Store on the same devices. If enough apps decide they rather develop for the Alt Store without the rules of the App Store, that’s where people will migrate if they wish to continue using said app. This happened on the Mac already where some developers decided to build their apps outside of the Mac App Store due to constraints. Whether you agree or disagree agree with Apple here, or wish for there to be alternatives, this is a factor that shouldn’t be ignored.
