creative commons licensing of models #406

Creative Commons do not recommend that CC licenses be used for an open source software license (https://creativecommons.org/faq/#can-i-apply-a-creative-commons-license-to-software) but it seems that many of NetLogo's model commons models are by default licensed under the CC-BY-NC-SA licenses (according to https://github.com/NetLogo/NetLogo/wiki/Licenses).

Is this intentional / by design or a holdover from the past? At the comses.net CML we are planning to migrate all of our CC licensed models to as close as possible / equivalent OSI approved licenses in the coming year to better support extension and reuse of models.

I believe the most problematic part of the CC-BY-NC-SA is the non-commercial clause which AFAICT is not supported by any open source license. CC-BY-SA is pretty close to the GPL.
