Back to basic : Can you paid offline and not used IAP and still maintain an account so both iOS and android can used your paid system to do say Netflix. If so you cannot argue their pricing … it is apple iap. Or Google iap. You are using their payment system. If any paid content or game must use their iap and forced to pay … then there is an argument whether the set price is fair. Like is Mac Pro is fair. If you do like it is there any alternative. Given there is two players … For low end developer … For high buck developer … Price discrimination is really a monopoly way to do things. Or tie-in sale. Not sure forcing apple to do it is right.
