Yeah.. I have all the respect in the world for Haifeng's talent and I totally understand (and agree!) that open source developers need to be compensated one way or another, and I don't want to get into a debate that could lead to accusations by people who don't know the full story, but there are definitely some sour grapes over the whole situation and some of the pull away from smile has more to do with feelings that not everyone involved is acting in good faith more than issues about GPL exactly.
