I'm not on legal-talk, so this mail is going out only to Talk-US. I'm happy to have it forwarded.
We had a license BoF organized primarily by Mapbox (Eric Gunderson and Alex Barth) with participation from Foursquare (David Blackman), on the topic of the license and its effect on geocoding data. Steve C, Henk Hoff, Paul Norman, Richard Fairhurst and many others attended. My understanding of Mapbox's issue, paraphrased, is that they have potential clients with lawyers scared of the ODbL and license status of latitude and longitudes returned from addresses geocoded against OSM.
As I understood it, the end result of the discussion was that the ODbL may or may not apply in this case and that Mapbox should submit some specific uses cases to the board to illustrate their specific concern so we can all stop blathering about whether the license is good or bad and move on to useful particulars.
In other words, what the 20120522 LWG meeting notes say.
