"Drawing on top of other apps" seems to be the way that they have implemented their lockscreen replacement. I have seen a glitch recently which indicates that the default lockscreen is actually running underneath. I'm fairly certain that they would use "retrieve running apps" to pull back information about how their competitors' apps are being used on phones. That could certainly be a competitive advantage in the mobile space.
