I should apologize since I misunderstood the fees being collected; they are the gas fees as presented in the Wallet app (I'd been thinking the separate app they release that includes the exchange trading, which has transaction fees). It's likely that the gas fees as presented by the Ethereum network are simply being passed along to the app user, which is definitely not the same as I'm suggesting. If Cash App charges their own fee (ie, it's not a bank fee that Cash App is passing along to the consumer) then I would actually expect Apple to want to claim their cut of that fee. At least, that would be consistent with how they've gone after this in, e.g., the Epic case. (Different type of in-app "purchase", but consistent considering who would be receiving the profit of the fee is the app developer.)
