We need laws and social norms where filming a stranger and uploading it online is considered a serious unacceptable offense regardless of the device. I find it absurd that today is completely acceptable to just film an unaware stranger and put the video online, especially since that the majority of the videos are about making fun of them or humiliate them.
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.
It's amusing to always have this US-centric view touted as some ultimate truth while lacking any nuance.
I live in Germany and here there is absolutely an expectation of privacy in public spaces. The individual rights (privacy) are balanced with the collective rights (freedom of press) and both are allowed to exist, because based on the context of the situation one right can prevail on the other. To give you some simple examples: if I go to a public event, a political manifestation, then no: no expectation of privacy. But if I am walking around with my family in a park, yes there's absolute expectation of privacy even if I'm in a public space. Context matters and it's impossible to have just one broad and vague rule covering anything. Also keep in mind that a public figure automatically has lower expectations of privacy than a private citizen. While I can sue a paper for publishing a picture of me slacking at work, a public figure most likely cannot or would lose in court because the right of the people to get informed of his behavior is higher than his right for privacy. Who gets to decide? A healthy judiciary system, not "those in power".
Another interesting nuance of the law in Germany is: it's almost always illegal to take pictures or video of people that show their suffering or struggle. You cannot take a video of a man having a mental breakdown for example. Is this universal? No, of course a journalist will take a picture of a suffering man in the cold to send a message about inequality. If he ever will be sued it will be the judge to decide if in this specific instance the right of the individual or the right of the collective right should prevail.
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.
