Indeed if ADP contributes to each article he can license it anyway he wants under the joint copyright theory as joint copyright holders can have nonexclusive licenses. humm. Food for thought. As Boorstein states:A joint owner cannot sue his co-owner for infringement".
Since any first version is published before a second version, I would think any wikipedia-article is a cascade of derivative works. Surely that's not the same as a joint copyright.
According to your logic, anyone could change a few lines in a GPL-program and relicense it anyway they want.
