CDDL has nice properties. And really it&#x27;s just an improvement on the MPL 1.0. There are good reasons to choose the CDDL (it&#x27;s a file-based not work-based copyleft so the implications with stuff like linking are clear). It just really bothers me that we have licenses which restrict you from combining two works to create a new works that provides more guarantees of freedom than one of them. It&#x27;s frustrating that by creating free software we now have different factions because we can&#x27;t <i>use</i> other&#x27;s free software.
