If a user is in close confinement with someone they fear will lash out at them if they test positive, for one. Off the top of my head, lets say you take an Uber home and the driver now has your home address, you don't know if they will try and attack you.

This is an example off the top of my head, as other comments in this thread have explained, violence against people who have the virus is happening around the world and is something that must be accounted for in these protocols.

Edit: a link to a story from another comment (https://www.washingtonpost.com/world/the_americas/coronaviru...). I hope you can see that this technology can worsen this.

The system doesn’t say who your affected contact is, only that you have one. The driver has no way of knowing it was you.

If you have a Bluetooth receiver logging the different IDs you've come in proximity with and when, its easy to deduce who the positive user is by who you were in proximity of at that time.

This is why the Framework only reports matches with a very coarse granularity.

At what time? It could be any user you’ve been in contact with for two weeks.
