I'd love that citation if you can find it, not because I don't believe
you but because that sounds like a couple very interesting cases.

Actually, this was an argument for (and for some people, against)
Wikipedia switching from GFDL to CC-BY-SA.

Even if the courts do say that images in an article constitute a
derivative work under law, they *still* might not be considered one
under CC-BY-SA, because CC-BY-SA has *its own* definition of
"Collective Work", and says that "A work that constitutes a Collective
Work will not be considered a Derivative Work (as defined below) for
the purposes of this License".

Of course, in the case of OSM mash-ups, we're talking about images and
images, mashed together in a way that makes them appear as one image.
Much much more likely to not be a Collective Work, though I suppose if
you overlay them in javascript after downloading them separately
you've got an argument (so long as you don't print them out!).
