Okay.

Yes, that is the point. If they have such a service, then somehow
they must get to that information.
And there is only one source in the world from where they can
originally get my address, which is - me.
Then they make a business of selling my own information back to me -
and I would like to know how they do that.

This is in fact just a typical case of: <how do other people get to 
your address in order to then sell it?>, only this time executed on
the instance of an IPv6 /64, so the usual excuse <you participated in
a public competition> would probably not hold.

! At least for my IP the geo information I get from there is simply junk.

Mine is not junk. Or it is, depending on the viewpoint...
In other words, I am wondering if it is really a good idea my Mexican
and Uruguayian cloud-dependencies being associated with my private
home address (which they are).


cheerio,
