> ""public health" is now likely to be a part of the surveillance justification tool kit too"
I don't have any specific examples, but this article gives a good gist of what might be at stake. [1]
I think this is a key quote
> "The Snowden disclosures came twelve years after the initial implementation of the Patriot Act, and it was only last year that the U.S. Court of Appeals for the 9th Circuit ruled that the subsequent dragnet surveillance employed by the NSA may well have been unconstitutional."

All state governments had initially ensured the public that the data was not available to LE, but none of them had actually passed legislation to make it unlawful until journalists discovered that the Police were using the data.

Of course that didn't stop police from still going into some places and demanding the data. But doing so was a clear breach of law.
Every piece of personal data you collect creates a pull factor for various actors to abuse said data, which is why you shouldn't collect more than you need, you should delete (or anon/pseudonymize) it once it is not needed anymore or you should collect it in such a way ot wouldn't be useful for state actors.
I am amazed how the German Corona-Warn-App was designed with these principles in mind. They managed to allow people to register into locations while only storing the data locally on your phone. Your phone then downloads the data from the servers in an non-revealing way and queries it for warnings/positive cases that have been issued in these locations at that time. If yes, you get a warning and you can decide how to proceed with this without having any other actor knowing of this.
This software is a piece of art from a privacy standpoint.
