Etc is indeed orthogonal to the software freedoms, but the FSF does not focus on it.
There is a slight confusion here and it is the line between the FSF and the GNU project -- the GNU project (nee RMS) started the FSF to support it -- so by extention it has always focused on the same issues as the GNU project. Specially in its infancy. Later, the FSF has broadend its scope, and several of the issues you raise are issues that the FSF has concentrated its efforts towards. https://www.fsf.org/campaigns/ has a very good run down on current, and previous campaigns. For example, with regard to privacy: https://www.fsf.org/campaigns/surveillance/
