I just solved it: If Facebook Ads (which are obviously bought for an in—app experience for others), I will now introduce a different pricing model to my app: you pay for a subscription of another person. And another person pays for yours. This way, the IAP clearly doesn’t result in your own app experience and hence, should be exempt from the 30% cut.
Or how about let users buy gift card or apps local currency(trading app). Which could then be used for anything within the app or can be transferred. That way it's no longer a purchase of digital good buy exchange of currency
I would think in that setup you'd have to have it such that you subscribing for another person would not guarantee that another person would subscribe for you. In other words, some people subscribing for others would not receive a subscription themselves, and some people _not_ subscribing for others would still receive a subscription paid for by some other user(s). Basically, you'd pay for a subscription and the benefits would go to some random user that is not you.
