Of course, the other issue is CC licenses are confusing enough as it is. This seems to suggest that Commons endorses the non-commercial license in some sense.

This license combination seems to be created solely to make commercial use as hard as possible whilst salving the uploader's conscience that it is still "free" (as it is technically...). If we just retag them to GFDL and move on would there be an issue?

Should we disallow PD or minimal licenses which allow later versions
to be made non-free?

I don't see how this is any worse.

I suppose you could make an argument that -nc looks more okay than it
is... and as such this is more of a problem normal licenses which
allow a work to be made non-free.
