I don’t have a clear opinion on ‘font-awesome’ yet, but I have some
comments: (1) only some of our font packages are built from source
(though I think we should do more of that), (2) the font might be
considered “non-functional data” rather than software under the FSDG,
and (3) the font is a “free font” under a license (SIL OFL) that doesn’t
have a clear notion of corresponding source like GPLv3 has.
