@PrincessConsueIaBananaHammock I feel exactly the same. I am not overly precious about it. But I would like to know more.
I find it quite unsettling.
I think it's the level of manipulation people are trying. It's been a common theme since this started.
If you ask questions about the app, you are part of the problem not solution.
If you arent comfortable with not knowing how they will use it, you dont care about the '10s of thousands of people whose lives could be saved by downloading the app'
If you point out that it wont work without mass testing, you sre being stupid and of course they will do that. Even though theres no sign they will be doing that at all.
Its like the 'buying hair dye while at the supermarket makes you a murderer' all over again.
People genuinely believe that any sign you arent fully complying, without asking questions, makes a person morally corrupt.
It's weird.
Oh and someone actually used the line 'download the app, save lives' 
And of course each few days South Korea and china are brought up and random things they have done have been hailed as the single solution.
Last week so many posters saying the fact that china and SK made wearing masks mandatory is the reason they have low numbers.
Before then it was mass testing
Before that it was that no one was allowed out, even for exercise. Just once every 3 days for food, alone.
Now its the tracking of people.
If their numbers are accurate, its likely to be a mix of everything.
One poster claimed that masks (not even proper masks, just fabric over your mouth) stopped spreading 100%.
