[OSM-legal-talk] CT clarification: third-party sources

[Eugene Alvin Villar]

Not so simple.

I'd much rather have the share-alike on the underlying data to a
CC-BY-SA map than the map image itself being share-alike. Sharing the
underlying data is not a requirement of CC-SA licenses. So if we go by
your definition, CC-BY-SA is NOT share-alike because the data is not
shared at all.
