As having all those databases being released might be good for the 
people wanting the data, it brings no benefit to OSM.

The purpose of ODbL is to keep data open. That's great.

My opinion is:
For OSM the thing most contributors favoring a share alike license model 
really want is a a clause which forces data consumers to grant a license 
to OSMF to incorporate modified/exended data back into OSM database.

ODbL does not contain such a "merge" clause. We could start merging 3rd 
party ODbL into OSM. But then have a hard time to fulfill attribution 
requirements. And an even harder time to get rid of the data in case of 
another license change in the future.

We need all contributors to agree to the contributor terms, granting a 
license to the OSMF to re-distribute the data.

Maybe we can change the license one more time to an OSM-ODbL. Not only 
requiring to release data as ODbL but also granting OSMF the same rights 
as in contributor terms.
