Very interesting analysis. If you filter by "Use Apple Google Exposure API" you should get only the official apps (one per country). Those look a lot better than the unofficial apps. None of the official apps use the Facebook API, but a few use Google Firebase and the official Swiss app sticks out for using AWS.
