Yes, exactly. We have been extremely worried about the opportunity for more pervasive surveillance, as well as the use of that surveillance to limit or gatekeeper our access to goods, services, and benefits. We know that measures taken in response to crises often hang around long after the crisis passes, and then get put to further uses. We’ve already seen governments in Singapore start to use Covid tracking data for other uses and I wouldn’t be surprised if that was happening in some places in the U.S. as well.
We also worry that these measures are regressive - that is people with resources can easily get things like Covid passports that are up to date and correct - and people without cannot.  And since those are often the communities more at risk for the virus, its impact ends up being exactly backwards. The people who need the protection the most get it the least.
