We have been discussing the need for the Fair use rationale with Fair use images on wikiversity. Here's the url=https://en.wikiversity.org/wiki/Wikiversity:Community_Review/Fair_Use.
As Wikiversity is the only WMF project specifically dedicated to education, teaching, and research. (It's on our Main Page.) Here's the quote: "Wikiversity is a Wikimedia Foundation project devoted to learning resources, learning projects, and research for use in all levels, types, and styles of education from pre-school to university, including professional training and informal learning. We invite teachers, students, and researchers to join us in creating open educational resources and collaborative learning communities." Requiring the non-free media rationale for fair use images has already been met. Can we get WMF-Legal opinion on this? US Copyright Law does not require such a rationale for education, teaching, or research uses. One of us is convinced that we must provide it. I'm convinced that en.Wikiversity as the WMFs only declared educational project, has already been provided for all such Fair use declared images.
