You are obviously reading 
http://www.opendatacommons.org/licenses/odbl/1.0/ , section 4.5 in a different
way that I do.  

     " a. For the avoidance of doubt, You are not required to license Collective
Databases under this License if You incorporate this Database or a Derivative
Database in the collection, but this License still applies to this Database or a
Derivative Database as a part of the Collective Database; "

For me it looks like business users can feel safe with their data if they do not
make derivative databases, for example by enhancing their own data by taking
tags from OSM database. Drawing their own data on top of OSM basemap is OK,
isn't it?
