Inadequate credit for OpenStreetMap

OpenStreetMap and our community of mapping volunteers are currently not adequately credited by mapfit (not meeting legal requirements or our recommendations), with only a small mention buried in their "Legal notices" page https://www.mapfit.com/legalnotices (Even here the credit is very minimal, with no description of what is being used, and still failing to comply with our legal requirement to mention the license)
