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.

I really don't understand the attitude.

Because it's duopoly, there are no other options. You're free not to use alternative stores or so-called sideloading.

My understanding is that you can do both on Android.
