I've just seen this article. I have read the entire thread, and am really horrified with the response of a couple of OpenBSD developers, especially Theo de Raadt who seems very, well, I'll leave the the adjective up to you.
I would be really angry if somebody copied chunks of my GPL code and then re-licensed it without my name on it. I would say Michael Buesch took a very aggressive stance, but I think I would do exactly the same in that situation.
I really hope Theo de Raadt doesn't represent the majority of OpenBSD developers.
