Ian Eiloart -- Actually, clause 4b requires that derivative works credit the Original Author (the wiki).
Deego17:05, 14 September 2005 (UTC) Ian, well this comes down to the GPL vs BSD debate. I guess, when I meant "protect", I meant protect the right of the user to copy, not protect the attribution for the author (not that I am opposed to the latter).[reply]
BTW, discussing this on #wikinews, people have mentioned how the self-propagation clause of copyleft licenses leads to incompatibilities among variuos licenses. I would like to say that:
I am not sure that is strictly true. GPL, I think, does not ask that derivatives be GPLed too. It just asks that derivatives provide the same rights and restrictions. FSF maintains a compatibility database.
Even if that were true, the license of emacswiki (see the bottom of that page) is an example of n-al licensing under a host of copyleft licenses, perhaps with a view to address this problem. This license is also followed by an irc-bot which freely shares with emacswiki.
