To me this looks like an indirect way for Apple to extract more money from developers. Since it's so easy to set up a campaign that does not lose money (it's pay per install), imagine _every_ developer setting up a campaign with their app's price as maximum bid (ignoring revenue shares to simplify). Lots of installs, but zero revenue for developers.
