I cannot directly comment on the upstream issue tracking system, but I
can add my comments here: feel free to forward them upstream or to
point upstream to the Debian BTS bug log.
Upstream seems to claim that there's no problem, since they are in
compliance with the old (troublesome) Unicode license.
It's possible that they comply with the license terms, but that's
not the point.
The point is that the old Unicode license makes those files non-free
and that those files are included (in verbatim or modified form) in the
Ruby interpreter reference implementation!
Hence, Ruby v2.2 (or v2.3) incorporates non-free parts!
In detail, enc/trans files carry a license notice that:
(a) only grants right to make copy for "internal distribution", thus
possibly failing DFSG#2
(b) only grants right to use the information supplied "in the creation
of products supporting Unicode", thus failing DFSG#6
(c) does not grant any permission to modify the file, thus failing
DFSG#3
In case upstream are not familiar with the Debian Free Software
Guidelines (DFSG), the following URL should be mentioned:
https://www.debian.org/social_contract#guidelines
As far as generator.c is concerned, its license notice also has
issues (b) and (c) explained above.
I hope the problematic files may be replaced by more recent versions
released under the current Unicode license:

This will depend on whether we may or may not consider the old Unicode
files as de-facto re-licensed under the current Unicode license...
Please try to at least investigate this (perhaps by getting in touch
with Unicode, Inc. and asking for clarification).
I hope this helps.
Bye and thanks for pushing in the right direction!
