free means free. its an abstract ideal...
you do not live in a country where people are free, 'free country' and 'liberty' are politically charged terms which evoke particular ideals, which don't directly map to the meaning of the word 'freedom'.
a big part of society is that we willingly give up certain freedoms for the greater good - this is what law is all about.
in this particular case i think its clear cut. the GPL stops software from being free compared to an MIT or BSD style license...
