Could someone please explain exactly what it is in the license that
make it non-free?  Perhaps the above statement isn't accurate any
more, I believe the license has changed over time.  If some term make
the file non-free, I can forward this problem to someone at Unicode
Inc. that responded to my request to change the Unihan license earlier
(which was completely non-free).

I'm quoting http://www.unicode.org/Public/4.0-Update/UCD-4.0.0.html
with the current license terms below.
