Thank you for the clarification, as I said, there are exceptions which are few and far between for the rule, with this being a huge carveout I missed - selling physical goods is exempt.

But if you want to pay for in-game goods (subscriptions, gems, skins, whatever) or an app outright Apple takes 30%. I know they charge Netflix the 30% for their subscriptions, but wonder about e.g. tickets/passes for transit.
