Not to mention that your android/ios device is still shipping a bunch of bluetooth tokens for "track and trace" system. Cryptographically signed to you.

That's a bit of an oversimplification that makes this sound more concerning than it is. Not that it's 100% un-concerning, but I suggest that anyone concerned about this read the linked docs. It really was designed to be quite privacy preserving, though it's obviously a difficult challenge in this context.
Isn’t this GPS data to see where Covid has spread? Even if your name is anonymous, a GPS point that every day goes to your work and then your home is surely you?
Most probably, yes. But how would you know who I am and where I live? And if you do know both of those things, are there other ways of figuring out my routines? Yes, there are.
Keeping the name out of that data does a lot for privacy. With a name in there, you could use the data to find my name and figure out my address. Without the name in there, you don't know which point I even am without knowing some of my locations from another source.
Correlating data with another source is half of what data brokers do, so I wouldn't really say that is any level of privacy protection.
It is encrypted ciphertext rotated every 10m in lockstep with your Bluetooth identifier.
You will need to turn off your Bluetooth if you want to stop advertising a rotating random number.
The only difference with the contact tracing is that a key, on the device, can correlate the ciphertext. I have it off because the utility was never demonstrated.
