In my country when they bought out the great coof track and trace that was useless and not that many people bothered with, Apple said hold my beer! The next auto update that most user leave on, and agree to without thought, had its own version and from there on in was highly trackable - and everyone hit the agree button!

In Australia, they were told their track and trace system would all be anonymous and absolutely never ever ever, ever not never be used by the police to track people.

3 weeks later the Police made arrests using the track and trace app and locations.
