I know, and I have experienced their "harm" a few times before. This one, on the other hand, is considerably better than others (it doesn't do any magic, and you can pick what to kill). Also, most apps it cannot kill itself, but rather acts as a shortcut to the app info thing so that you can force stop stuff. This particular app has saved me many times when certain apps went rogue (and yes, clean master sucks compared to this...).
Why is Android doing this to me? I like having control. There is no way I am rooting this thing until it is at least 2 years old. Is there a non-profit way around? I though that I had a right to control my device the way I wanted to.
