It is related to side loading. Apple for a long time disallowed side loading (even now it barely counts). So if you wanted to sell anything to iPhone users you had to go through Apple's store and potentially compete with them at a 30% tax disadvantage.

Even with the current side loading changes, which are EU only, they still take a major cut and still dictate who can and cannot run a store.

So I agree with you that the App Store, like other stores have the right to dictate what they do and do not sell. They do not, however, have the right to say that they're the only store allowed, or that any new store must pay them money.

Also, I'd be hesitant of using Google's behaviour, certainly its current behaviour or current market position, as justification for what is okay for others to do.
