Boy, do you just take everything presented to you at face value in life? I'm sure there is a lot more behind the scenes. Yes, in theory, the idea of highlighting and promoting apps is an excellent and novel idea. However, the consequences of this and even the actions a lot of developers are taking behind the scenes are much more than simply kind-hearted gestures to help fellow developers. They're screwing with the charts, they're taking paid promotions rather than true editorial to highlight apps they've selected, and they're using push notifications as an advertising means.
Look into things a little deeper before just believing everything people say. This has been going on constantly. Apple rejects apps, developers get their 15 minutes of fame spinning the story, when really they got rejected either because they used unpublished APIs or other technical things like that, that the general public doesn't know about.
