This is a pseudo reply to Jason Calacanis for what he said about using an Open Source game engine to build a game in This Week in Startups #54, Ask Jason segment. I believe Jason is implying that you can’t make money with open source software(that’s not a support contract variant) directly, but it’s a good resume builder. True there aren’t any big billion dollar open source companies, and companies like Red Hat make money off support, but I don’t believe he’s correct.
