This really does change my opinion of both Joel and FogCreek, and certainly for the worse. I wonder, did FogCreek actually prevent Ted Unangst from contributing to OpenBSD as a side project while he was with them? If so, that's horrible. And how much have FogCreek, StackOverflow, and other companies that seek to greedily arrogate the entire creative output of their employees benefited from open source software began and continued as the very side projects this blog post cautions against? Utterly hypocritical.
I second the call of another poster: we need a professional association (union) of the kind that lawyers, doctors, and dentists have. IEEE and ACM could easily function as such, and in fact, they already provide many of the same practice standardization and continuing education functions that other professional associations do. All that's missing is the rent-seeking behavior to ensure we earn what we're worth and keep employers like Joel honest.
