So what does "freedom" mean, he uses so much? Is there a clear consensus on that? I believe allmost everyone says he or she is for "freedom". Slavers and Nazis used the term freedom as well as the actual slaves, workers, whatever.

So yeah, he also defined his version of "freedom", but labelling sounds very RMS to me. Also the strict wording of "ethical" software, meaning only the licence he favors is ethical and good and everything else, not.

A good place to start would be this essay: https://www.gnu.org/philosophy/free-sw.en.html - which he wrote because the term "free software" (as you correctly observe) would be too fuzzy.

RMS has his faults but ambiguity is not one of them. He really bends over backwards to be careful about explaining what he means.
