Well, it's not really share-alike downstream either, is it.
If someone takes an ODbL licensed planet.osm and adds their own data to it
then there are two reasons why we may not be able to have these
1) They can impose some incompatible license conditions on their added
2) They refuse to agree to the Contributor Terms
What attributes of share-alike are successfully implemented by ODbL+CT? Is
it really a proper share-alike license in practice?
