I really find it hard to wrap my head around that explanation. Just to be clear, there is nothing wrong with monitoring and reacting to the volume control. There is nothing wrong with taking pictures. There is no "functionality" used that isn't permitted. What they did was -- for users who overtly WANTED the functionality -- tie the volume control to taking a picture, only when their app is front and forward. Apple doesn't like this because they want to keep every app in the painted lines. However, yes, it's primarily a kick in the balls of every user who went out of their way, demonstrating that they wanted this usability. Apple has a stunning arrogance when it comes to how the product that you paid for should work.
