I'm fairly sure that a comment on this thread by an Apple employee would result in a pretty quick firing. It's a pretty tight ship over there.

Ive worked for Apple and it is no different to any other company.

A policy was put in place that governs the rules around when apps should be rejected or not. The rules haven't really changed for a while now.

The current version of Dropbox SDK violated the in app purchasing rules which app developers unwittingly used. Hence their apps were rejected.

People forget that the employees who are auditing these apps are the equivalent of customer service reps. They aren't developers and their job is to be objective and simply follow the rules.
