The modern marvel that are credit cards or debit cards run at low single digit percentages. And they are getting a ton of margin out of those; so much that in the EU, they capped fees at 0.3%. And those transaction fees actually pay for something, like customer protection, SLAs (not a shitty status site) and no, the credit card company doesn't add unskippable ads on top of the checkout process or advertise a scam clone version of what you are trying to buy to you. You tell me if the app store fees provide 100x as much.
