I think you mean "dictatorial" or "totalitarian". "communism" is something quite different.

Because it's selling well, it's hyped, the apps actually (looks like) it will sell better, it's easy (for some people) to get started, and it's actually really one of the better mobile platforms to develop for, despite the complaints.

The iphone is the coolest smartphone on the market. Innovative software authors don't like working on boring platforms.

Until the iphone's cool status changes it will continue to recieve the most hype.
