We use maps extensively in our products and Mapbox has been a belessing eversince we started using it. I would argue Mapbox is far better suited for development and product integration than Google Maps is. It is developer and user friendly, offers a wide range of mapping and layering products. It easy to use and affordable small and medium sized businesses.
Given how very little the TomTom announcement actually says, I've read it as a (desperate?) attempt to pivot into the mapbox market. In any case, nice to see OSM eating the mapping world.
