@zverik Partly true. In my (questionable) opinion, there's a fundamental difference in the motivations of Overture and OSM. Overture is a commercial interest group while OSM is a public interest collective. One is driven by profit motives and enablement of "industries" and the other is not explicitly aimed towards such an outcome (or at least doesn't seem to be).
It's not that they won't talk to each other. It's just that there's nothing to talk. There is no overlap in intentions.
