There is a third way.  OSM could allow multiple different licenses.  Then
each contributor can choose which license to publish under and each data
consumer can select the appropriately licensed data for the use they have in
mind.

There are technical obstacles to achieving this - but we are all more
technically skilled than we are legally skilled.

At the simplest level we would need a PD layer and a CC-BY-SA layer.  The
main difficulty would be to provide some method of linkage between the two
layers and some rules about how to link (eg a PD segment cannot link to a CC
node, but a CC segment can link to a PD node, etc).

Neither option is ideal.
