Something I just noticed on an application using "Mapbox streets" map tiles. When you click on the "Terms & feedback" link, you fall down here: https://www.mapbox.com/about/maps/
And what I read is that "OpenStreetMap contributors create and improve our map data". I find the "our data" "clumsy" for the best case or "dishonest" for the worst. When I contribute to OSM, I'm not improving the Mapbox map data, the "your" map data, displease you, Mapbox friends. I'm working for the OSM map data and you take advantage of it.
