If anyone is really concerned about it, they would probably first try convincing some of the people who sit on FSF Award Selection Committees, FSF working groups, many of whom I know to be *actively promoting* use of "Linux", "Open Source", FOSS Terminology and *severely critical* of "GNU/Linux" and "Free Software".
The award committee includes people who support "open source" and who call the system "Linux". But they don't speak to the public in connection with our awards, so this does not cause a problem.
When you say "FSF working groups", what does that mean? The FSF does not have anything that we call working groups. Perhaps FSF India has some working groups; is that what you mean?
