The response on pediapress :
« If I'm not mistaken, all Wikisource wikis are CC-by-SA licensed, so
essentially no contributor has to be mentioned. I agree that /if/
contributors are mentioned, the list should not be wrong, but I'll lower
the priority for this ticket. »
But CC-by-Sa says :*
« Attribution*. You must attribute the work in the manner specified by
the author or licensor (but not in any way that suggests that they
endorse you or your use of the work). »
So, the correct mention of contributors of Wikisource is refused. That
disgusted me.
