The tactics Apple employs are so outlandishly anticompetitive it’s almost comical. Sure, it’s not a smartphone monopoly, but in the iPhone app market, Apple reigns supreme - and it is a tyrannical reign.
It's a real stretch to suggest that Apple is a monopoly because they control their own platform. By that definition anyone who has a closed platform is operating a monopoly. Is Netflix a monopoly? Fiverr?
One of the principles of competition law is prevent a company from abusing a dominant position or to prevent a company from obtaining a dominant position through abuse. Apple does not have a dominant position.
