GPL compliance issues are tearing Joomla! apart
Joomla! project leader Louis Landry and his colleagues want to protect the project they love. That's why, after two years of allowing proprietary plugins for the open source CMS, the group has decided to ask third-party developers for voluntary compliance with the terms of the GNU General Public License, under which Joomla! is licensed.
Those developers are complaining that it's unfair for Joomla! to reverse its position after "a bunch of companies spent millions," according to one developer employed by a company that markets the proprietary extensions. Landry says he and the Joomla! team were wrong to have allowed the exceptions, and a return to compliance is essential in order to legally protect the open nature of Joomla!.
