That's what almost every project advertising it is free of non-free stuff is: some other project with the non-free parts removed, nothing more. Trisquel (Ubuntu), linux-libre (linux), libreboot (coreboot), etc. When your sole selling point is lack of non-free stuff, there is no need to invest time adding anything else.

E.g. linux-libre is just a big script that removes the nonfree parts and firmware support; they just run it against every kernel release with minor tweaks and that's their new release. libreboot is similar.
