Definitely wearing my Apple fanboy hat here, but...

I'm going to propose that there has been ~1 legitimate case of this in iOS history. Maybe 2?

I feel like for the most part, the original guidelines were pretty solid. While they weren't complete and have been changed significantly since the original publication, most of this has been to add guidelines around new features (like push notifications), and to clarify rules. This clarification could be read as Apple changing their mind, but I reckon almost every instance has been 'obvious' and that it would almost always be apps that were knowingly skirting way too close to the rules, and not acting within the spirit of the guidelines, that got burned.
