No the problem here is that a business wants X money, to sell thru Apple (and similar) they have to add 30% to what they want, whereas other payment platforms offer a much lower cut.

However Apple does vet apps and focus on security somewhat (altho Google's project 0 seems to do a better job at finding bugs for Apple), however 30% is far too much even for what Apple are offering their customers.

In an ideal world, Apple customers need to be told: "you will be charged extra buying through Apple to help pay for the protections/quality that our platform offers you".

However, Apple explicitly disallows both telling users that they're being charged more and why, and that they could get it cheaper elsewhere.

Regardless of whether Apple are still allowed to charge x%, the first step it to get Apple to allow developers to tell the customer about other payment options and for Apple to explain to their customers why it costs more, then customers can make the decision for themselves.
