We should evaluate the criteria for:
- What shows here
- Sorting order
- Leaving the site (should we have a privacy warning when you leave the site, like T107085: Implement privacy warning for 3rd party data source on Wikivoyage)?
considering the issues of privacy, open source, and open content.
E.g. Why is OpenStreetMap only 4th? Do we need to list this many? Are these sites all copyright-compliant? There are old issues like T166467: Request: Remove Wikimapia from list of external map services in Kartographer.
