Also, I suspect open source follows a pareto distribution (5% of the projects get 95% of the contributions). And no contributors is probably better than being overwhelmed with low quality contributions and feature requests.

I am pretty convinced that this is a major issue. I am looking for a solution that would allow unrestricted open source use while restricting closed source use. For example, freely combine with a BSD licensed open source project without imposing any restrictions on it (GPL), but disallow combining with a closed source project (unless a commercial license is used).
I am wondering if such a license (or license strategy) already exists.

Ok, I hear you there :) This will sound weird, but I do not even consider myself a Windows developer anymore (despite being an ex-MSFT and writing Windows kernel mode drivers). I am writing to you from a Macbook Pro and I make a living these days writing Mac and iOS apps!
