Which monopoly is Apple abusing?

iPhone apps.

If it helps, think if Windows apps had a 5% Microsoft tax and had to be approved by Apple.

I assume you mean approved by Microsoft.

When they were found in the US to have a monopoly, they had around 95% of personal computer operating system share. Apple isn’t even close.

		Really? What would you estimate is Apple's market share of iPhone apps if it's so far below 95%?
