As I understand it (and I might be wrong), there are basically two types of open source projects regarding copyright and Contributor Agreement.
The first type are projects where contributors hold exclusive copyright on their contributions. These projects often does not require contributors to sign CA, and project owner could not change the license for the project without permission from every contributor. Linux is a notable example of this type. The second type are projects where contributors transfer or share copyright with project owner. This requires contributors to sign CA and allows project owner to redistribute code including your contributions under a different license (proprietary or open source). Clojure is the second type. -- Mikhail -- You received this message because you are subscribed to the Google Groups "Clojure" group.
