Hi,
After thinking a while I came to the conclusion that the Collaborative Virtual Workspace License (CVW) http://cvw.mitre.org/cvw/licenses/source/license.html is not a Free Software license for the following reason.
General (5) "In either case, if you transmit source code improvements or modifications to MITRE, you agree to assign to MITRE copyright to such improvements or modifications, which MITRE will then make available from MITRE's web site."
This sentence allows the following scenario:
- you make modifications - you assign copyright to MITRE - MITRE releases your modifications under a non free software license and publish them on their web site - you are not allowed to use your own code - you have to remove your own modifications from your machine
I know this is unlikely but it's permitted by the license. Therefore the freedom to modify the software is crippled, hence the license is not Free Software.
Do you see any flaw in this logic ?
