I thought this article was relevant to the class discussion. It details how Google traffic data was being used by many to track the movement of Ukrainian refugees and Russian and Ukrainian troops. Google has since made the decision to cut off all live traffic info in Ukraine for the time being.
“Google Maps’ live traffic data works by incorporating location and speed information from smartphones with the app, then using it to show in real-time how dense traffic conditions are in certain places, or how busy those areas are overall. When Russian President Vladimir Putin launched an attack on Ukraine last week, however, some spectators realised the feature could also be used to provide open-source insights regarding the whereabouts of military operations.”

The article does include some NSFW language in the form of quotes from Ukrainian officials.
