Agreed TFA is misleading. Apple and Google refused to allow governments to track individuals through exposure notification apps and forced client-side, privacy-preserving notifications. I’d imagine HN would have supported the Apple/Google approach where everything’s local and anonymous rather than what many governments initially proposed where identity and/or location was logged by the apps. (I also agree that privacy-preserving exposure notifications are better than invasive tracking ones, especially in the US where the citizenry expects a right to privacy)
