Yet people generally don't have this problem with applications on their computers. Why is that? Because it explicitly tells you what it can do? Or because there's a way for them to restrain themselves? Anyway, is there a way to block apps from using certain APIs? I.e. restrict them more? Ideally with some dummy interface returning empty whatever so the app won't crash. Like you can restrict apps from accessing network (though they do expect to not have Internet connection usually).
