Gerard, I will not only think Internet. I hope others
will not think only USA. If the point is "If we use a fair-use image, a commercial
organization can at least take whole Wikipedia pages and re-use them." Well, this is
not necessarlily true outside the USA. So fair use images should be banned for the same
reason that applies to NC's.
The way I understand the current official position is; NC pictures are
not allowed. Fair use is only permitted on a language project. The idea
here is that this allows to have some local law kick in. This is a
nonsense because people edit on every project from more countries that
the "local" country. For some of the minority languages, we have a
situation that often people abroad to the "local" country are more active.
I do agree with you that having "fair use" pictures should be banned as
well. I also think that we should have a narrow band license where there
is a specific good reason why you want to use pictures and where it can
not be allowed to make derivations (for instance logos of organisations).
