To me, anyone who work in tech and dismisses the Exposure Notification framework as "surveillance" is no different from an anti-vaxxer. The app does 3 things on your phone: 1) continuously exchange Temporary Exposure Keys with other phones with EN enabled, and 2) periodically download a list of TEKs, compare to locally cached list of TEKs to determine if you were in close contact with a COVID positive patient, and 3) in the unlikely event when you are tested positive, work with your Health Authority, use a one-time code to upload your TEKs to the key server. If you are really paranoid, you can do 1 and 2 with just a battery powered Raspberry Pi Zero (someone has done that and was previously posted to HN but can't find it right now) which should be net beneficial to you. But if you just don't understand this framework please stop spreading FUD.
