Who said anything about opensource? The issue at hand is closed source and profit.

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.
The reason I doubt it means opensource because that's the equivalent to musicians handing over their source files.
Ultimately those who can adapt, will adapt. And they will inspire others.
