Wikipedia Moving From GFDL To Creative Commons License
FilterMapReduce writes "The Wikimedia Foundation has resolved to migrate the copyright licensing of all of its wiki projects, including Wikipedia, from the GNU Free Documentation License to the Creative Commons Attribution-Share Alike 3.0 License. The migration is scheduled to be completed on June 15. After the migration, reprints of material from the wikis will no longer require a full copy of the GFDL to be attached, and the attribution rules will require only a link to the wiki page. Also, material submitted after the migration cannot be forked with GFDL "invariant sections," which are impossible to incorporate back into a wiki in most cases. The GFDL version update that made the migration possible and the community vote that informed the decision were previously covered on Slashdot."
Without RMS's approval, this could never have happened. The FSF wrote a clause into GFDL 1.3 specifically to allow this to happen.

Basically as it became increasingly clear how much the GFDL sucked in practice as a wiki licence.
