> What's next - 30% of my pizza price goes to Apple because I ordered it on my phone?

You joke but this already happens with places like DoorDash. They take 30% of the order from the store owner after adding their own additional fees to the order that customers pay.

Someone I know owns a pizza store and his prices are 30% higher on DoorDash but some people still pay. The big difference is it's not a monopoly. He offers regular delivery at normal store prices and 95% of his deliveries go through that.
