Replace Google Maps with OSM
WSC 6 (at the latest) should no longer use Google Maps. Instead, OSM (via Leaflet?) should be used, so people can use GDPR compliant maps on their websites. OSM allows using locally hosted Tile servers as well as remote ones (e.g. https://tile.openstreetmap.de).
Imho, there's no reason to continue the use of Google Maps, but I know, that this change is backward incompatible, so I suggest switching in WSC 6.
This has been already suggested at https://www.woltlab.com/community/thread/260837-alternative-f%C3%BCr-google-maps-openstreetmap/ … Yet I'm curious whether WoltLab may see the necessity now?
I'm aware, that this was already requested a few years ago. But time has passed, and we're somewhat closer to v6. Furthermore, it is labeled as "Not planned", therefore it won't be considered anymore until a follow-up request pops up.
