You used the phrase 'open source' 9 times in your three paragraphs, but didn't mention 'free' or 'freedom'. (Hmm, the F in FOSS may count as one veiled instance.)
Talking in terms of freedom for people to use free software however they want makes more sense than trying to dance through the forest of varyingly-free 'open source' licences.
I think we have to separate definitions from strategy/goals: the OSI open source definition and he FSF Free Software definition—the latter of which seems to be what RMS views Free Software as entailing—a remarkably similar. The difference seems to be that RMS and the FSF view preventing non-Free software as an important goal, and this prefer licenses which tend to have the effects of preventing downstream non-Free derivatives and encouraging people to relicense other software under them, whileany others in the FOSS universe prefer promoting FOSS creation and use to preventing non-FOSS software..
But I think he described it very well. Open Source, I am opening it and I don't care about Your Freedom, nor my Freedom or anyone's Freedom. And you should not judge me whether I care about it being Free or Not.
This is the crux.
No two people agree on what this actually means, and it sidesteps any discussion of freedoms.
