Hello, This is in /usr/share/doc/phpnuke/copyright:
Note from upstream author: ############################################################################## # I M P O R T A N T N O T E # ############################################################################## # IMPORTANT: I saw many sites that removes the copyright line in the footer # # of each page. YOU'RE NOT ALLOWED TO REMOVE NOR CHANGE/EDIT THAT NOTE. If I # # still see this problem happening I'll need to take extreme measures that # # can include: to change the PHP-Nuke license, to encrypt some parts of the # # code, stop distributing it for free and in an extreme case stop developing # # it. The decision is in your hands. # # If you do not agreed with this simple rule, delete all PHP-Nuke files # # right now and move away from it. Thanks. # ############################################################################## I think this is not good for the same reason as the BSD advertising clause. The notice is: "Web site engine's code is Copryight (C) 2002 by PHP-Nuke. All Rights Reserved. PHP-Nuke is Free Software released under the GNU/GPL license." This would seem to also prohibit modifications and derived works, since a proper copyright notice would reflect the status of the modifier.
