I didn't realise that, I pointed at Wikipedia when I suggested using an
icon in CSS :-)

There's a comment on the FontAwesome GitHub repo [1] that gives a lot of
sources indicating that the OFL is not compatible with the GPL so I
think we should be using something else here, at least in the main
distribution.  If individual sites want to do something different that's
their choice.
