Is SFLC Shooting Open Source in the Foot?
The academic article by SFLC about ZFS is troubling and may unintentionally shoot free software licensing in the foot.
When I was at Sun (as part of the team that released the Java Programming Language by starting the OpenJDK project) I often heard community concerns about the CDDL license. At the time the big complaint was about the "Choice of Venue" clause.
I got involved because Sun had developed many essential Java libraries and distributed them under CDDL. The community requested a more permissive license and I was able to convince internal project leaders (and Sun's lawyers) to make a licensing change for a handful of these projects. And there was much rejoicing.
Based on my experience in helping Java to become open source I came to appreciate the legal hacks on copyright which make open source possible. It's the free software license which uses copyright to enable sharing (vs. the default of disabling sharing).
