It's not an "edge point". One can discuss the inherent moral goodness or lack thereof of using a certain tool, whereas you seem to subscribe to the view that something is bad if "evil people" use it and not otherwise. With similar train of thought one may argue that nuclear weapons are good for the US to have but not for an evil empire such as the USSR (actual argument that was used by people), or a gun is bad when it's used by a criminal but good when used by someone in self-defense.

You see that in these cases one can discuss the merits of the application but also argue about the whole ban of the tool itself, irregardless of who's using it.

Also if you hate HN noone is forcing you to be here.
