This doesn't necessarily mean a FSF-Cetified distro. LibertyBSD is fully free and isn't on their list, as is Hyperbola. Debian can be made to be fully free (and is by default), Fedora can be made to use linux-libre with a few easy scripts, rendering it fully free, Gentoo and Funtoo can use linux-libre, etc.
If you are, what have you given up for the sake of freedom? If you're not, what's stopping you?
