Germany: Deutsche Telekom gives user location data to Robert-Koch Institute

The German mobile operator Deutsche Telekom announced in a press conference on RKI Live that it had passed on, anonymised, its users' movement data to the Robert-Koch Institute to study the extent to which the population would follow the government's restrictions. RKI president Lothar Wieler said this data is also available for purchase, but was given to RKI at no charge.
