It's his work, and he had every right to pull every module he hosts there in protest. If this was a walk out or some other form of protest, nobody would be calling him a dick, I think that's a little out of order.

That said, the system is definitely broken.

His reaction to the Kik thing is probably where he was at fault, I think it would have been reasonable for him to back down there; companies, in the US at least are obligated to protect their IP in order to retain their rights over it (as far as I have understood from various discussions on HN), but perhaps the forceful lawyering got his back up?

Also I have no idea of jurisdiction of any parties involved, I just assume US.
