I like the Affero comparison and I will now use that instead of
upsetting people by comparing the licence to BY-SA. ;-)

Great, that makes sense.
Under section 4.3 of ODbL 1.0, you have to attach a notice to the
Produced Work letting recipients know where they can download the database.
If the Produced Work is copyleft/share-alike/reciprocal licenced, will
the offer apply to derivative works/adaptations of the Produced Work?
So if I make a derivative of a map you make from OSM data, are you still
liable to provide the data to recipients of my derivative?

So in the case of copyleft Produced Works there's two parallel
distribution graphs of derivative databases and derivatives of Produced
Works, and the licences don't interact due to the way that downstream
users of Produced Works are not bound by the ODbL.
