I don't want to force people to do anything. If people want
derivatives of their work to be used in GPL software, they should
license their work under GPL.
GPL is not a bad license for software. But it's not a good license
for photographs, or maps.

And CC-BY-SA can't add a source requirement, because the lack of it is
vital for the way many forms of non-software work.
Under the theory of the GPL, a die-cast toy would need to come
packaged with the original mold and an injection molding machine, or
at least with an offer for one at no charge valid for three years.
Maybe the GPL doesn't actually say that. I haven't really considered
the case thoroughly enough to say. But the principles of the GPL just
don't apply to everything which is copyrighted.
