> What Apple does is bad but they don't tax 30% of every transaction. Apple isn't taking a 30% of your Uber or DoorDash, they charge 30% for sales made on their platform for digital goods and services redeemed on that platform.

You're mischaracterising the situation. Apple taxes 30% of all transactions made on apps other than exempt transactions. The food and tangible services you mentioned are exempt categories. Apple takes a 30% cut of all sales of digital goods and services transacted on apps on their platform, regardless of whether the goods are "redeemed on that platform" (whatever that means). Of course Apple has built a byzantine maze of carve-outs, exemptions and counter-exemptions that muddy the waters and give them great power if you're a small developer without the resources to fight them for your rights.
