If we restrict Apple's incentives to be purely monetary, then we have to wonder if the reputational damage is less than their cut of users being scammed.
I would argue that the reputational damage is worth more, strictly monetarily. Apple is an incredibly valuable brand, estimated in the hundereds of billions of dollars[0], and they are understandably protective of it. If <2% of the top 1000 apps are scams (from the article), and Apple periodically catches scams and helps unwind them (2/3rds of the apps the Post reported were removed), I don't think Apple is making all that much money here. Remember that Apple does't keep its 30% cut when a transaction is refunded.
