I mean, that’s kinda exactly what I said, Apple taking a 30% cut of any transaction that occurs on their devices/on apps downloaded from their store makes no sense, though I will add that Patreon takes a 8 - 12% cut depending on how much support they give the creator. As far as Steam goes, to my knowledge they don’t take a cut out of in game purchases, only purchases that occur strictly on their platform. (Also I don’t think they charge everyone the 30%)
