Hang on.... I maybe know why....
Didnt they use Google Maps before? Im almost 100% sure they did, look now, it is OpenStreetMap.... and that has much less features and possibilities. Now it makes sense. They migrated from Google Maps to OSM, because Google introduced that API limit, which obviously would not be enough for them and they probably do not want to pay Google for higher quota... thats why I also said that in my template I want to keep using Google, because it is by far the best and for our purposes, 10000 views/day is of course absolutely sufficient.
