That's a really good question.
In my head, I'm imagining someone early in the morning posting a flyer up on a bulletin board downtown.
Throughout the day many folks walked by and took photos of the flyer with their cell phone.
At the end of the day, the original person came back and removed the flyer.
IMO, at the time that the folks took the photo of the flyer, that flyer was public information. It remains public information even after the flyer is removed[0].
This isn't a great analogy of mine, and has plenty of holes, but was interesting to me after I read your comment. I know it was in the context of doxxing, but I think it's pretty interesting philosophically.
I think something similar applies to photos taken of other people in public spaces. Both the person who took the photo and the subject of the photo are no longer in that physical public space, but the actions took place within that space.
I think something similar applies to digital "public spaces". But what does a public space even mean in the context of walled gardens[1], etc.
[0] you then run into the question of what happens if someone posts non-public information, publicly?
[1] are digital walled garden communities that different from physical communities that gate access, whether free or paid. Whether information shared within those contexts are public or private is an interesting thread as well.
