Delta emulator triples Apple's prices to encourage external clicks (opens in new tab)

Because they have a monopoly, and practices like this can be enforced with that monopoly

If they get booted from the app store, they cannot sell on IOS devices (and no, the one or two people willing to side load a paid app don't count :)

They're a monopoly and use it to harm consumers for profit.

15% for handling all the stuff necessary to do proper customer service isn't unreasonable. everyone wants their cake and to eat it too. they already got the ability to list their emulator, it feels like a lot of begging going on, which honestly a teen writes an app and it gets big and now years later wants to make an entire career on it even though it was never permitted by apple and feels like they have a right to complain? especially when their product is focused on piracy (let's be real here). feels pretty duplicitous.

It does. Apple handles the refunds automatically. They also give you a chance to provide more information about the user’s usage so if the user used the app a lot, Apple might reject the refund request.
