Umm, if you want it so that some people are exempt from sharing their
data, then having a share-alike license is the wrong license. Ergo, if
you want a share-alike license, people have to share their data. If
you want people to not share some data, you want a non-share-alike

Don't call them "business users", since that's just smearing lots of
other businesses. Call them "people trying to wriggle out of the

No. That would be avoiding the whole point of the share-alike license.
If they have geographic data that we don't have, and they mix it with
OSM data, then the whole point is that we end up with access to their
geographic data. It's called share-alike! Not

Really, if people (businesses, charities, individuals or whoever) have
data they wish to keep private, they can still use OSM data
internally. If they want to "Publicly Convey this Database, any
Derivative Database, or the Database as part of a Collective
Database", then they can't avoid the licence.
