No, I don't assume anyone knows what the four freedoms are; I assume only that, if they possess an average level of intelligence, they can do a quick web search for "free software" "four freedoms" and read the first search result. Then all your accusations of deception, subversion, not telling them what those freedoms are, and any issues with agreeing on what those freedoms are evaporate in mere seconds!
Perhaps not a fair expectation of YOU, but for everyone else, it's valid.
