What is the difference between free and copyleft? Fundamentally, a document is free if ''it'' may be used freely: freely read, freely copied, freely modified, and freely distributed (see http://www.gnu.org/philosophy/free-sw.html or http://www.debian.org/social_contract#guidelines). A document is copyleft if ''its derivatives'' may be used freely.
When I say 'free' I mean free as in cost and free as in freedom.
Well, then the non-copyleft free licenses should fall under that definition as least as much as copyleft ones. There's no difference in cost (the only difference would be non-commercial licenses, which neither of you seem to be advocating), and in freedom they're more free.
... We can have this argument, but let's be clear about what we're arguing over. AFAIK, ''nobody'' is advocating that Wikimedia publish non-free articles. (There is the issue of incorporating fair use items ''within'' articles, such as quotations and images, but that is a different discussion.) The question is whether their freedom must be protected by copyleft.
I'm advocating the full use of the word free (no cost and copyleft).
Then you have a strange meaning of 'free'.
"You may do with it what you want, provided you mention my name" is more free than "You may do with it what you want, provided you mention my name and give others the same rights and obligations".
