The top-level comment was talking about a monopoly, and you talked about Apple having a monopolistic position. In markets where Apple is in not in monopolistic positions, nor is it a monopoly, the problem is the anti-consumer and anti-competitive practices that enable it to put itself between market participants, not the position. Even if Apple doesn't seek a monopoly, the app distribution practices are the problem and would lead to the same undue value extraction.

I'm taking monopolistic position to mean a grossly dominant market position short of a monopoly. If you meant it as engaging in "monopolistic competition", that's another concept entirely that's irrelevant here. I also took monopolistic behaviour to mean behaviour seeking to monopolize.
