I guess what I'm trying to say is that there is, and can be, such a thing as "ethical hacking," but perhaps it's not coterminous what vendors and others might claim it to be. The meanings of words evolve over time, sometimes for the worse (cough "literally"), and sometimes for the better. Groups have also reclaimed derogatory words through concerted action.
It's a complicated human activity, so of course there are ethics to it. But I'd strongly recommend not using the words "ethical hacker" next to each other, because that term has more meaning than you probably intend.
