> You're saying there might be some expectation of privacy even in public?

Not parent poster, but yes!

What people expect are outcomes. The mechanics they know of for how data is/isn't available is merely how they reach their reasonable expectation.

I expect that almost nobody I meet in public is a Stasi informant.

P.S.: To put it another way, a major purpose law is to clarify and codify the expectations the people. Not just expectations of privacy, but expectations of when we have liberty to observe or record.

We expect that our faces might be captured on someone's vacation photos in public, surviving as an anonymous and unconsidered background detail, and that we can take our own photos like that without getting permission from everyone in the background.

In contrast, we don't (didn't?) expect all the photos to feed into a mega-panopticon that that does facial-recognition on all subjects and cross-references us over time and space while running algorithms looking for embarrassing, criminal, or blackmail-able events.
