This isn't really an arm thing, pretty much all processors have
protected modes... What you're describing doesn't really have
anything to do with android, but has to do with Linux itself (or any
modern operating system). So the way that android handles you not
being able to touch other people's processes, is to just use Linux.

This sounds like a bogus explanation given because they couldn't think
of a better reason. In this case, "you downloaded a bad app" is like
saying "you got a virus."
