This implies the business is setting the price, which if so, sure I guess. But "creator economy" applications as one example also fall under "digital goods", which means a user is setting the price on a platform to provide a service for $X, the platform takes $Y cut, and then pays the user $X - $Y, but then Apple wants 30% of $X. It's absolutely insane because most platforms out there don't even charge a fee that high so in order to cover the Apple tax they either have to make $0 per transaction and also pay creators less, or just charge consumers $X + 30% up front.
