Open source software initially was a head-scratcher: “How can you make money selling something for free?” But once open source advocates clarified the meaning of free – “Free as in speech, not as in beer” – the open source economy took off.

Commercial software vendors have tried to defend their walled cities with both marketing pitches and legal threats while simultaneously lowering their drawbridges with an “if you can’t beat ‘em, join ‘em” strategy.
