* Francesco Poli: > Or are trademarks entirely orthogonal to Freeness issues?
They are not entirely unrelated. The DFSG explicitly mentions mandatory renaming clauses in licenses, and deems them to be DFSG-free. The Mozilla trademark license seems to be rather harmless at that because they give permission to retain the command names. The prime motivation when the DFSG were written likely were TeX and its fonts. TeX's licensing status is worth a discussion of its own, but Debian didn't want to miss this piece of software.
