that's exactly the point. ODbL is not a suitable license for data being 
imported into OSM.

Date being inserted under the contributor terms come with much more 
freedom to be used by OSMF (and the membership deciding about the open 
license used) with respect to the license chosen for distribution.

So what happens is that a user enters data to OSM (with CT agreed), then 
data is distributed as ODbL by OSMF. Then extended by 3rd party.

That extended data i now less free to use from an OSM point of view.

For OSM it would be much more convenient when the license says "You are 
allowed to use the OSM data, but when you change it you give OSM the 
right to merge back your changes if they want to".

Probably we should adjust the license one more time before too much 
incompatible data is being imported.

And I'm asking for stricter regulations considering imports. Data not 
compatible with future license changes must not be imported at all. 
Other mappers are building their changes on a weak foundation.

Maybe time to open a new thread as we're moving away from the original 
point of satnav data being released to a generic discussion.
