I am responding to a poster claiming 37% of Apple's profits are from the App Store. I'm not sure what their source is; it seems at least somewhat believable to me, since the profit margins for Apple on App Store revenue are extremely high (analysts estimate 78% [1]), so even if App Store revenue is a smaller percentage of total revenue, the other revenue costs more, and those costs cut down their percentage contribution to total profits. Regardless, it's fairly widely reported that the App Store is much more lucrative for Apple than the Play Store is for Google. 1: https://www.marketwatch.com/story/how-profitable-is-apples-app-store-even-a-landmark-antitrust-trial-couldnt-tell-us-11622224506 https://www.marketwatch.com/story/how-profitable-is-apples-a...
