Directly from the article: "Programmers should give away their software and make money from consulting."

I read that as meaning open source, what do you take that to mean? Maybe my requirement that it be open-source is too restrictive - I'd be just as happy to see an example of a freely available closed source game that earns its creator a decent living.

In regards to 2dboy, while I think it's certainly an interesting economic model, which has a lot of potential, I don't think it's a counter-example of what the article is arguing in-favor of since it's still not free.
