Derivatives of WordPress code inherit the GPL license. <a href="https://web.archive.org/web/20110812015435/http://drupal.org/">Drupal</a>, which has the same GPL license as WordPress, has an excellent page on <a href="https://web.archive.org/web/20110812015435/http://drupal.org/licensing/faq/">licensing as it applies to themes and modules</a> (their word for plugins).</p> <p>There is some legal grey area regarding what is considered a derivative work, but we feel strongly that plugins and themes are derivative work and thus inherit the GPL license. If you disagree, you might want to consider a non-GPL platform such as <a href="https://web.archive.org/web/20110812015435/http://www.s9y.org/">Serendipity</a> (BSD license) or <a href="https://web.archive.org/web/20110812015435/http://habariproject.org/en/">Habari</a> (Apache license) instead.</p> </div> </div> </div> <div id="footer"> <div class="wrapper"> <p> <a href="https://web.archive.org/web/20110812015435/http://wordpress.org/about/privacy/">Privacy</a> | <a href="https://web.archive.org/web/20110812015435/http://wordpress.org/about/license/">License / GPLv2</a> &nbsp; &nbsp; See also: <a href="https://web.archive.org/web/20110812015435/http://wordpress.com/?ref=wporg-footer" title="Hassle-free WP hosting">WordPress.com</a> | <a href="https://web.archive.org/web/20110812015435/http://wordpress.tv/" title="Videos, tutorials, WordCamps">WordPress.TV</a> | <a href="https://web.archive.org/web/20110812015435/http://central.wordcamp.org/" title="Find a WordPress event near your home">WordCamp</a> | <a href="https://web.archive.org/web/20110812015435/http://jobs.wordpress.net/" title="Find or post WordPress jobs">WP Jobs</a> | <a href="https://web.archive.org/web/20110812015435/http://ma.tt/" title="Co-founder of WordPress, an example of what WordPress can do">Matt</a> | <a href="https://web.archive.org/web/20110812015435/http://wordpress.org/news/feed/" class="rsslink">Blog RSS</a> </p> <iframe src="https://web.archive.org/web/20110812015435if_/http://www.facebook.com/plugins/like.php?href=http%3A%2F%2Fwww.facebook.com%2FWordPress&amp;layout=standard&amp;show_faces=true&amp;width=450&amp;action=like&amp;font=lucida+grande&amp;colorscheme=light&amp;height=80" scrolling="no" frameborder="0" style="border:none; overflow:hidden; width:450px; height:80px;"></iframe> <h6>Code is Poetry</h6> </div> </div> <script type="text/javascript">_qoptions={qacct:"p-18-mFEk4J448M"};</script> <script type="text/javascript" src="https://web.archive.org/web/20110812015435js_/http://edge.quantserve.com/quant.js"></script> <noscript><img src="https://web.archive.org/web/20110812015435im_/http://pixel.quantserve.com/pixel/p-18-mFEk4J448M.gif" style="display: none;" border="0" height="1" width="1" alt=""/></noscript> <!-- --> <script type="text/javascript" src="https://web.archive.org/web/20110812015435js_/http://s.gravatar.com/js/gprofiles.js"></script> </body> </html> <!-- web10.luv.wordpress.org --><!-- FILE ARCHIVED ON 01:54:35 Aug 12, 2011 AND RETRIEVED FROM THE INTERNET ARCHIVE ON 04:56:05 Dec 12, 2024.
