I think there is a continuum, from fully supported proprietary executable to tar dump of abandoned code. When I pick an open source library to use, the continued active development, documentation, and support community around it are my main criteria. Much the same is true of commercial software. I have little interest in downloading some random source code off the internet. Maybe that's not what's for sale on these sites but that's what it sounds like from first glance. If you're selling commercial components, why not set up your own website and sell it there?
