If that explanation is true ^, then it's pretty rich, because Apple recently aimed to get 30% of virtual experiences offered through Airbnb. How would those not be considered "outside goods and services" when they involve people outside the app providing goods and services? [0] Others are saying Apple doesn't see it as an "in app purchase"; however, I can click "Place Order" for an ad in the iOS app... I'd call that an in-app purchase! Can all companies let you buy digital stuff within the app with non-Apple payments or in a bill-you-later manner? Just ads?
Almost certainly there have been behind-closed-doors discussions on this, as the line has been arbitrarily drawn (either way) to include/exclude this massive company from the 30% tax. Indies don't have the same clarity on the rules; for example, Marco Arment's app Overcast sells ads, but doesn't complete transactions in the app because he was worried he'd need to give up 30%. Like with Apple's quiet program that let Amazon and a couple other token companies get a separate deal on content-app rules [1]: how can small companies on the store know when to press Apple on some rules and not on others (without retaining lawyers)?
It's just baffling because Facebook has recently whipped up quite a stir [2] around Apple requiring 30% of creator revenue, yet none of the articles mention this point about Facebook ads getting/not-getting a 30% tax for (probably the better part of) the past decade ... their bread and butter!
Furthermore, Facebook is whining about Apple making IDFA tracking opt-in on iOS, yet this company has benefited HUGELY from the fact Apple didn't do that from the start AND somehow decided not to charge 30% on its ad buys on mobile.
