You shouldn't expect privacy in public spaces. That's the nature of public spaces. In the US, freedom of press means anywhere public means you have no expectation of privacy, and should comport yourself as such; don't do anything or wear anything in public you wouldn't want to be recorded.

This is why paparazzi exist and how they operate. It's the dirty, dingy cost of having a free press, freedom of travel, freedom to hold public officials accountable, subject to the same laws you are; you can't waffle or restrict or grant exceptions, because those inevitably, invariably get abused by those in power.

The difference is public vs. private spaces. The supreme court in the US has defended the right to record videos in public. But if someone walks into my home, or my 3rd space, etc. with one of these on actively recording that should absolutely be criminalized and enforced.

>the majority of the videos are about making fun of them or humiliate them

That's just nonsense. Your feeds seem to be polluted by what you are seeking out, as I've never seen a video on any service that shows humiliation of anyone.

I watch a lot of 1st ammendment audit videos, and that is never about humiliation, though many people end up looking very ignorant of the laws concerning recording in public which is in the 1st ammendment.
