There's a huge difference between the historical intent of that principle and the way that these days everyone in a given space can be exhaustively recorded and tracked 24/7.

This saying isn't even true. Many countries have cultural expectations and legal structures providing some level of privacy in public. The very first GDPR fine issued stemmed from a business security camera that needlessly recorded people on the sidewalk.

The ease of mass surveillance and analysis/tracking makes it worse. Machine powered automatic analysis and tracking is more than just video recording. I hope that difference is apparent.

I actually have, by law even :)
