I read that link but it doesn't say anything about MapQuest Open using Mapbox and only discusses their consumer product: http://www.mapquest.com http://www.mapquest.com MapQuest Open is separate from their main product and commercial developer offerings: http://open.mapquest.com http://open.mapquest.com I don't see anything on the MapQuest Open website that indicates they use Mapbox to serve their OSM tiles.
