I noticed the other day that HappyCow <https://www.happycow.net/> uses
OpenStreetMap tiles loaded from maps.wikimedia.org.
I guess it's a good thing (they're very visible in their niche and at
the same time it must not be a lot of traffic), although not a primary
purpose of the service. I'd argue it's a way to promote the importance
of privacy, because now you don't need to query Google to find a
restaurant with their internal search.
What cases of third-party usage of maps.wikimedia.org come to your mind
which could be considered positive examples?
