MUI4 is closed source, so the real question is the one I already linked to: Did they get 2006 MUI4 source code from Stuntz (or whoever) or did they completely reverse-engineer it? None of these two possibilities would be illegal per se.

As said, MUI4 has been closed source all along.

Please enlighten me :-)
