Controlling what happens on your systems is not anti-competitive. You can’t just re-define words to mean something that’s the exact opposite of what they are. The locked down system of Apple and consoles is hair biggest value add. It’s not “something I tolerate to buy an iPhone”. It’s why I buy an iPhone. They make so much money because their control of their own product makes it better. There is no such thing as a “monopoly” on your own hardware. It’s literally impossible.

Google is a monopoly because they are controlling the behavior of competitors with their market position. That is always a monopoly. Controlling your own product never is.
