Aw, geez, and here I tried to avoid these debates. I used "open" to try and imply that GNU's license will keep the source code "in the open", as "open" implies something different from "free". I'm not going to argue that one is better than another, or that one gives more rights to derivative users or not. That way lies politics and madness :)
