http://wiki.openstreetmap.org/wiki/Open_Data_License_FAQ#What.27s_wrong_with_the_current_licence.3F

"The main problems that have come to light over time are:

    * The CC-BY-SA licence was not designed to apply to databases of
information and therefore has shortcomings when attempting to protect the
OSM data."

ODbL protects against the database right and against contract law.

"    * The method of giving attribution is somewhat impracticable for a
project with many thousands of contributors."

The ODbL handles attribution differently from BY-SA 2.0 , allowing BY-SA
2.5-style indirect or project attribution.

"    * Limitations make it difficult or ambiguous for others to use OSM
data in a new work (eg mashups) "

The ODbL codifies OSM's consensual haullucination that mash-ups are not
derivative works. ;-)

So the ODbL *does* attempt to address the issues that have been identified
with BY-SA for OSM.
