I thought it was kicked out of the iOS App Store for using the private APIs, after it was accepted. That is fair on its face, because those are the rules Apple set. However, the F.lux developers pleaded with Apple to open up the APIs needed to implement their software and were ignored. Then Apple copied their functionality as a built in feature of the OS. So the full story doesn’t make Apple look good.
