Yes, that's my reading, unless you invoke some superior right to "fair
use" or "citation" or whatever applicable in your country; which would
of course make any copyright discussion obsolete. - I regularly use
screenshots from proprietary web sites in my talks and I believe I have
the right to do so without even looking at their license, but I am not
100% sure that this is within the law.

Correct. I think that CC-BY-SA creates an incentive for the secretive
data provider to, instead of combining his own data and CC-BY-SA data
server-side and delivering it to the customer, furnish the customer with
a bit of software and feed him CC-BY-SA and proprietary data through
separate channels. That way, the data is combined on the users'
computer, leaving him user with a dead-end undistributable (but usable!)
lump of data.
Surely a win for Freedom!
