One of the single best books on data collection, privacy, and ownership:

In short, once you hand your data over to someone else, Third Party Doctrine applies and you lose MOST of your protections around privacy, warrants, etc. This applies to banking, communications, library records, etc, etc. Almost anything done in public does not have the "assumption of privacy" and therefore gets even fewer protections (usually none).*

If we want to roll back the surveillance society, we MUST abolish Third Party Doctrine and enact data ownership rules. Unfortunately, there are a LOT of dollars flowing because those rules are minimal and weak at best.

* Not a lawyer but have followed and researched this one extensively.

I will recommend the 2018 book "Habeas Data" which explains a lot of the case law that got us to this point. (https://www.amazon.com/Habeas-Data-Privacy-Rise-Surveillance...)
