This is one hell of a peak capitalism comment - I already payed tons of money for the richest company in the world, no way I'm bothered them getting that another 30% cut.
Look through my comments and you'll find I'm not some "the free market will magically solve all our problems" ideologue. Monopolies / monopsonies are a thing, and both workers and consumers need to be protected from them. Your attitude would make sense if there were no other smartphones around, and it was "buy an iPhone or go without".
But there are plenty of good smartphones with alternate business models. If you don't like the fact that your apps are more expensive because Apple charges a 30% commission, then buy an Android and install a third-party app store.
