Blocking screenshots on this level sounds wrong. The operation system UI should make clear when and how other apps are recording the screen. As an app developer, I should not be bothered with avoiding screen captures. Breaking this functionality breaks the lowest common denominator of data sharing: Taking a screenshot. One of the reason to make a screenshot is just because an application misses a proper data export functionality.
