Hi!
We, as members of the open source community, would do well to wish him luck. Every one of us reflects the community, and snarky remarks make the community look childish. I would have preferred it become open source; Not because I plan to use it but because I want the community to benefit from the largest pool of code possible. Being rude to him will make the chance of him later changing his mind that much smaller. Why would you contribute to a community that has been rude to you?
I'm not rude. He is rude. We didn't ask him to convince us to release our work as open-source, and yet he uses it for his business. :-)
