Well, you came to the right conclusion, even if for the wrong
reasons.  But I figured you'd get to where I wanted you to go, one
way or the other.  It isn't non-free because of the XFree86 licences,
but because of other licences.  If you look at XFree86 as a whole,
you'll find that it hasn't qualified as FSF-free for years -- for
at least as long as the SGI GLX code has been included.  It was
not, as a whole, FSF-free before the change, let alone GPL-compatible.
Same after the change.  But then XFree86 has never factored in
those two licensing criteria.  If you or other distros have policies
against shipping software that isn't FSF-free, you shouldn't have
been shipping XFree86 since at least 4.0.  It isn't the modified
XFree86 licence (compare with the original BSD licence and especially
the Apache 1.1 licence, which are both FSF-free and OSI-open) that
suddenly makes XFree86 as a whole not FSF-free.  It simply hasn't
been in at least 4-5 years, if not longer.

The big deal you are all making about the GPL-incompatibility of
the modified XFree86 licence is really quite minor in comparison.
Lets face it:  Your real objection is to giving credit to XFree86
and its contributors.  GPL-incompatibility and FUD about FSF-freeness(*)
of the modified licence is just a poor excuse.

Anyway, keep researching the various licences and definitions, but
look at the content, and don't be misled by the labels or lack
thereof.  Maybe you'll make it to the next step too...

Enjoy your day.
