This is not an all-or-nothing scenario. The choice is not between an app that saves lives and compromises privacy, or no app and lives lost. Privacy preserving technologies exist, and now is the time to use them.

There is an additional technological cost, but that's what we should weigh the privacy costs against. The choice is between an app that doesn't care about privacy versus one that does.

Time is of the essence here. I agree that, all else being equal, privacy should be respected. However, if it takes multiple weeks to iron out all the potential privacy issues, this approach becomes much less effective.

We don't have enough runway to care about privacy, we'll just un-collect all that data once we raised!

Sorry for the sarcasm, but I buy this now as little as I buy it in other situations.
