"You are indicating that, as far as You know, You have the right to
authorize OSMF to use and distribute those Contents under our current
licence terms."

What are the "current license terms"?  Right now it means, what,
CC-BY-SA?  And after the CC-BY-SA content is removed it means ODbL and
DbCL?

At what point, if any, does the database become one where OSMF can't
switch back to CC-BY-SA without removing data?
