I read that link but it doesn&#x27;t say anything about MapQuest Open using Mapbox and only discusses their consumer product: <a href="http:&#x2F;&#x2F;www.mapquest.com" rel="nofollow">http:&#x2F;&#x2F;www.mapquest.com</a><p>MapQuest Open is separate from their main product and commercial developer offerings: <a href="http:&#x2F;&#x2F;open.mapquest.com" rel="nofollow">http:&#x2F;&#x2F;open.mapquest.com</a><p>I don&#x27;t see anything on the MapQuest Open website that indicates they use Mapbox to serve their OSM tiles.
