I think this COVID19 tracing app is the exact opposite of that, yet everyone seems scared of it. If the adoption is low, then it won't be effective, so given the responses on this thread I suspect it will fail - too bad, it could have offered some valuable info to people. This app seemed to me to be so much more benign than a simple Google Maps program that everyone uses every day to help them find a location or direct them in their car to a destination. Do they not realize how much data they are handing over compared to this anonymous COVID19 tracing app? I don't think so.What bothers me is how asymmetric the pros and cons are. The possibility of getting negative attention from police, tax authorities, and health insurance are horrible possible "cons".
