The monopoly Apple has is the paid mobile software market. The difference between software sales on the Google play store and and the iOS App Store are pretty staggering. I have no expertise in the law so I can’t tell you that’s it a monopoly in the US legal sense (if i had to guess, no) but it absolutely is one in practice. It makes sense that developers, particularly powerful ones like epic, would argue that it is.
That's a good point re the fact that Apple offers the only viable mobile paid software market place. For me it raises the question of whether forcing them via law/regulation to change their model would in practice have the knock on effect of destroying that market, making iOS more android like in terms of developer profitability for all but the Epic-like titans.
