in any case they are using a significant amount of OpenStreetMap data
and must attribute. They are actively hiding map attribution for all
screens with less than 993 layout pixels width (i.e. all phones and
most tablets):

https://www.wohnlagenkarte.de/css/e888f00.css

@media (max-width: 992px) {
    .leaflet-control-attribution {
        display: none;
    }
}

This alone merits a letter from OSMF. I have been lucky finding a
mention of osm hidden in the fourth paragraph of "über
Wohnlagenkarte", but it does not link to osm and which has no mention
of copyright or the ODbL.

The transforms they are applying to OSM data do not seem trivial to
me. Can someone explain to me why we are not interested in the data
about the residential quality of the land?
