It's not clear that any of these tracker proposals actually harm privacy. Certainly the government in most places can get this data from phone companies and correlate it themselves.
I think that's almost true but not quite true. The governments can get location data, but the location data is not that helpful at learning who was within virus exposure range of whom, or at learning who was actually within conversational range of whom (say, to spread ideas thought to be subversive by the leaders of a regime). What's being talked about for contact tracing is using Bluetooth or other means to try to measure that kind of proximity. So these would be new capabilities in addition to capabilities that already exist and those new capabilities might present new threats to people.
