Covid has been curtailed without the need for these apps (in all the places that opened up). Why do people insist on pushing them to people? There is no evidence they work, even when with months of testing. No matter how anonymized you try to make them, the authorities and evil state actors will find ways to abuse the data -- it's like a law of nature now that all data will be abused.
E.g. in case of a bombing or riots, the police can arrest bystanders and use phones to tell who was standing next to whom.
Pushing these for security theater has long term bad consequences. I was hoping people would know that after the 1000th repetition but alas, people are incorrigible
