about CC licenses
just for a short confirmation:
I have a package which is licensed under CC-BY 2.0
This page  doesnt specifically list CC-BY 2.0 but I found this page 
which explains why CC-BY 2.0 is not DFSG free.
My question is: is the resource as  still reflecting the correct reasons for
why CC-BY 2.0 is not DFSG free? Upstream is asking why CC-BY 2.0 is not DFSG
free and I want to point them to the correct resource or give them the correct
I am about to package software which is licensed under CC-BY 2.0 so it must
probably go into non-free. This page  also doesnt talk about CC-BY
3.0 but if upstream would change the license version to 3.0 then it would be
DFSG free, right?
