[What Do You Get in Return for the] App Store 30% cut

Haha, recently used a DTS Support Incident for an issue I would have liked to overcome in the UI.... and even after stating that my plan was to make it into the MAS, the two responses I got were basically "you need to override these private methods however Apple recommends against using private APIs, blah, blah."

My app isn't ready yet, and so I haven't submitted it to see what happens, but to this day, I still don't know what he was recommending me to do or if he was trying to say they would ignore the private API usage?

For a potential 30% cut, I agree with the OP that you should be able to get a straight answer.
