Apple doesn't let you disclose their 30% IAP fee to your customers
If it was closer to 5%, or even a fixed fee (eg: $1 per app sold), I would accept the narrative that it's a fee.30% of your business is not a fee, it's more like a partnership. Apple is, in practice, a business partner to each and every iOS developer. Except that they have total and absolute control of the business. If they shut you down on the App Store, you're done. Your iOS app is worthless on any other platform.I shit you not, I've personally had apps rejected by the review board because they didn't like the screenshots. Those were screenshots of the app itself.
