All of the licenses in Debian that impose a restriction on the license
of modifications either:

* only impose entry into a commons.


* are the QPL.

I think any license that imposes restrictions on the license of
distributed modifications -- other than entry into a commons, that is,
the same terms under which you received the work -- is non-Free.
