Sure, I think those privacy concerns are a little bit different.

I am slightly more hesitant about things like that, but at the same time I think that use of data has probably greatly helped their response in controlling the epidemic. Overall, I'm probably in favor of the use of this kind of data in this scenario, but the "slippery-slope" argument makes a lot more sense there to me.

While we've had epidemics and pandemics in the past, we've never had them with the intersection of shared personal data before. We haven't really had any time as a society to think about the utility or the dangers of this kind of approach.

Once the acute phase of the crisis is over, I'd love to see a lot of thinking go into how we can get the benefits of this kind of data while mitigating as much of the privacy downsides as possible.
