Equality source

Equality source is a concept that the terms under which the code source is made open by the copyright holder is done in such a way that the licensee obtains the same effective rights as the copyright holder, thus emulating http://en.wikipedia.org/wiki/Public_domain.

In terms of copyright law all code is either proprietary copyrighted or public domain. GPL code is proprietary code because only a proprietor or copyright license holder has the power to license his code under an open source license. It seems the BSD clause-3 is the only license which effectively emulates public domain.

GPL http://en.wikipedia.org/wiki/Open_source means that the terms under which the copyright holders such as Linus Torvalds, FSF and RMS licenses their code don't apply to themselves and their "corporate sponsors", establishing a master(licensor)/slave relationship(licensee).

Equality source must be used as the antonym of open source to designate the differences.
