I'm not saying that people exposing cheating spouses are breaking families. I'm saying that AM was by explicitly encouraging that. It's not just a random dating website, it's the website targeting married people and running campaigns saying cheating is OK.

I am definitely not arguing for shooting the messenger (I apologize if my comment was not clear enough about that) - what I want to say is that I may agree the boundary between "ok hack" and "not ok hack" may lie on the public concerns/private concerns line, but IMO one could argue that Ashley Madison lies on the "public interest" side.
