Users defend it because it’s a user friendly experience. The concept is good, even if you think apple’s cut is too high. Imagine going to a grocery store and needing to go through several different checkouts depending on which products you bought.

I'd take a couple different checkouts for a 30% discount on some goods. The problem for me is if I can only get their goods through their checkouts.

I do think the 30% is a bit absurd on reflection. I think OP properly framing it as 30% of our money is an important insight.
