I see what you are saying, and I understand what you are referring to.

It was stallman himself who, after working in GNU for years, went on the invent the concept of free and open software. I'm not doing any mash up. I'm referring to the 4 fundamental freedoms of free software as associated together by stallman himself and protected by the free software foundation.

If you could provide sources it would be useful as the history of these concepts is pretty much a living history. Since the people who coined them are still alive and still write copiously about the philosophical implications of the movement.

I have to say honestly I can't find anything that supports your comment. Perhaps only tangentially, if one assumes that some so far unarticulated and shadowy movement of Open source promotes only source available software.

Are you referring to Bruce Perens definition of open source that is used by the open source initiative? Because they are not antagonists of the free software foundation. While it's true that it also extends to proprietary but source available software, this has been considered widely a positive rather than negative. Although different points of view exist in the analysis of how the four fundamental freedoms interact.
