Their draconian control freak policies are, basically, an extension of their absolutely freakish focus on making the UI "perfect", yeah. Intolerance for UI flaws becomes intolerance for design inconsistency becomes intolerance for design diversity becomes intolerance for use diversity becomes intolerance for anything that isn't "the Apple way", whether it's software add-ons or use cases, or use methods, that don't fit their intent.

The first two (intolerance for design flaws and design inconsistency) are good. They just don't know where to stop :-}

(or, they do know where to stop, but they know that any cult requires that type of black and white "this is who are, and aren't" definition)
