There is clearly an "alternative mall" on the market, it's called Android. With 75% global market share they are the ones that are much more likely to be a monopoly, yet for some reason all the accusations are instead being leveled at the minority player on the market.

I don't even know why people are getting hung up on this monopoly thing. You can make a perfectly valid argument against Apple's 30% cut or their overly restrictive App Store policies regardless of whether they have a monopoly or not. Those arguments stand up on their own.
