Gould: Oracle to Red Hat: It's Not Your Father's Linux Market Anymore

While I know your post was likely meant to be humorous, you are forgetting about the effect of the GPL which effectively makes it no longer an exclusive right, and hence not proprietary despite being copyrighted.

I may own a thing at first, but if I donate it to the public, I no longer own it. Free/Libre software has been donated to the public. In the X/BSD copyright case, it primarily serves to remove liability from the donor. The copyright in the GPL case additionally serves to ensure that it stays public and is not homesteaded. In neither case does the copyright serve to retain exclusive right to the software.
