Apple's App Store is more akin to a Company Store[1] where you live in a town owned by the company you are utilizing for your lifestyle and their store is the only place you have available to shop. It was a scandal in the past as it's unfair to consumers while also being unfair to producers. The argument of "well you can just move/buy a different phone" did not hold up very well with society.

This unethical model is not any better in our modern world.
