We're way off topic now, but well. OSM is insistently not focused on a map, but on the data. On this data a lot of other mapping projects can (and are being) built. In central Europe, we have freemap.sk, which combines OSM data, hi-quality aerial imagery - for Slovakia only, these were shot by the government and are licensed in a way that they can be combined with OSM data - resulting in possibilities such as displaying bike paths over super detailed aerial maps. Also check out mapy.cz, they are based on OSM (outside of Czechia) and in some parts of the world can be switched to satellite/aerial imagery with roads overlayed over it.
