Some of the problems: If you get an alert, are you personally responsible if you aren't going to self-quarantine immediately and perhaps infect others after being notified? What use would a tracing app have if anyone could ignore alerts at will, because s/he has no symptoms and is afraid of job loss if quarantining?
On the other hand: What about people not using the app or just disabling bluetooth because they are afraid of being helt responsible? What if your employer, your supermarket or your health insurance demands that only users of the app are served/welcome? Are they allowed to check that you conform, even if the use itself is volontary?
I'm not against a tracing app, but lots of unsolved questions aren't even discussed openly.
