Exposure notification is not contact tracing. Questionable if effective contact tracing on mass scale without privacy violation is possible. At least Singapore contact trace and enforcement chain worked. Worse, A&G hubris in their solution and lack of cooperation with governments that wanted a proper contact trace solution bordered on insolence has caused preventable deaths. The fact that two platform owners could prevent the rest of the world from mounting proper epidemic responses is terrifying. Even more so if it's just a handful of employees dictating their culture to the rest of the world.
