I've pointed this our before. but anyway: we don't really care that much about the imagery licence as such as long as we are allowed to display it in the usual OSM tools. The real question are the rights in digitized vector data from that imagery.
The best situation IMHO is if the provider of the imagery clearly states that they waive any rights in such digitized data (which depending on jurisdiction they might not have in any case). If they insist that the digitized data is a derivative and licensed on the same terms as the imagery itself*, we need either explicit permission roughly along the lines of the contributor terms (while theoretically permission to distribute on ODbL 1.0 terms is enough, that implies that the data may have to be removed on any licence change, a lot of work that we probably don't want to have looming over us), or we need waivers on specific incompatible terms of the licence. The later requires that we determine exactly what needs to waived, something that we (aka LWG) haven't done for CC BY-NC in any version. Simon * this is naturally just one of many variants possible, but likely the most common. Commercial imagery typically has terms of use that cover digitizing and needs to be considered separately.
