The only license the Moodle Lead Dev knows, is what will make him the most $$. “All contributors give permission?” Are you kidding? You really think they even keep track of the contributors? This is a “community” open source project in name only–it operates like a privately held, commercial project and anyone who contributes to it should understand that fact.
Last Moodle version is under GNU GPLv3. How can they upgrade from GPLv2 version? All contribuitors give permission for license upgrade?
Thanks in advance, Marc.
