Yes it is. We have a pretty successful app in the iTunes store and as a consequence, we have privileged access to the entire team, including engineers and executives who advise us how to word the description of our app and telling us all kinds of tricks to increase downloads.
A few months ago, we released an Android app and since then, we have fallen into a complete Apple black hole. The Apple people we used to exchange daily emails with are not even responding to us any more.
Apple is very, very serious about exclusivity.
And probably feeling very, very threatened too.
