The other crappy thing is, even if the developer has a working version on another app store, there's no way (under the terms) to say "Sorry, you can't do that here, but here's a link to a version of the app that does allow it". I think even mentioning Amazon's app store ("you can also download this app in the Amazon app store", for instance) would be enough to get you banned.
