No, for free software to be "Free Software" it must respect the Four Freedoms (https://www.gnu.org/philosophy/free-sw.en.html https://www.gnu.org/philosophy/free-sw.en.html). GPL-or-other-copyleft-license happens to respect them, but so do the Apache, BSDs, MIT and other licenses which are not copyleft. Note: "Copyleft" as opposed to simply Free Software entails reciprocity, e.g., the "viral" part of the GPL. See https://en.wikipedia.org/wiki/Copyleft https://en.wikipedia.org/wiki/Copyleft
