Not all OSS has a price. All of the code I've releases is under a free license, not a restrictive one like the GPL. This does mean that companies can use my code in their proprietary projects, but that seems to have gotten me more contributions back instead of less.

I also think that a license which is too complicated for anyone to actually understand is simply too flawed to serve it's purpose, which was the original point of my post. This is completely separate from people not giving back to open source.
