I've been a bit out of the loop on this for a while, so please be kind to
the oldbie - what's current Wikimedia policy on adaptive reuse of Wikipedia
content into non-free publications?
E.g. Graphiq
https://www.graphiq.com/terms-and-conditions
http://colleges.startclass.com/l/1929/Harvard-University
and Google
https://www.google.com/intl/en/policies/terms/
https://www.google.com/search?q=harvard+university
I recognize that Google gives Wikimedia a lot of money, even if the
foundation isn't very transparent about that, but I'd think that doesn't
free the company from following CC BY-SA.
