Yes, of course I’ll install it.
But then, I don’t give a toss who knows who I am or where I live. Things which are easy to find out anyway. If the dishy bloke down the road arranges an assignation, or if I decide the time is right to break into the bank, I’ll just leave the phone at home.
After the pandemic is over, I’ll uninstall the app and/or get a new phone. But for now, in a time of emergency, things are different and some freedoms have to be put on the back burner.
Now, if they want to implant a tracking device into the back of my skull, or fix a tracker around my ankle I may object.
