Well, then shame on you for not looking at what it's about to delete.It puts a list right in your face. Nothing hidden from you. Then... for "touchy" files it even asks you to authenticate what you're about to nuke - again, listing what those files are and giving you a chance to abort.
Shame on me? I've never used it, and it would never touch my machine. I'm perfectly aware of how it works, but the absolute truth is that if you're an experienced enough user to avoid the significant pitfalls, you should be able to do the important things it does faster and easier without it. If you're not, then you're far too likely to run into trouble when using it.
Claiming you're not a shill doesn't convince anyone, btw, especially when you haven't been accused of being one.
