Thanks for all this :-)

The thing with that argument is that there are lots of people with data
and money who probably hold the opposite view, eg Ordnance Survey.
This was data only right, not cartographic interpretations eg maps?

Yes, I've been thinking about the latter.

IANAL. We have case law here in the UK where big company a (the AA) was
taken to court by b (the OS) because they copied their maps. The
clincher was that they also copied fake streets, easter eggs, trap
streets in the map. This gave away that they copied 'their' map. So does
it fall down because these are not facts, they're creative secrets? If
in your next conversation or otherwise you could ask about this it would
be super helpful.

It would be super useful if you could also ask 'can we use a CC license
as a contract? That is, if the data is not copyrightable, can we say to
people you may use this data AS IF IT WERE copyrightable, with this CC
license if they sign a contract / tick a box'
