Software freedom advocate and Columbia law professor Eben Moglen has resigned from the board of the Free Software Foundation (FSF).

Moglen, who has been on the board of directors for FSF since 2000, announced the news on his blog earlier this week. He will remain with the FSF and continue to offer his services as General Counsel on a pro bono basis.

Moglen has been strongly involved in the drafting of the third version of the GNU General Public License (GPLv3) for FSF over the past few years. With the release of the discussion draft on March 28, he wrote “that it’s time I began to think about life after GPLv3.”

His future involves managing the managing the Software Freedom Law Center (SFLC), of which he is the founder and chairman, as well as making a return to Columbia Law School as a lecturer. He also plans to add to his collection of writings on the topics of freedom and software, which includes such works as the dotCommunist Manifesto.

The FSF has not announced a replacement for Moglen on the Board of Directors.
