As someone who has no idea what this is: What's the context here? By the name I would assume violation of multiple privacy related cases, which probably justifies deletion from basically everywhere. But then again, I have no idea what's the deal here.
It was a series of videos taken in public where a guy would just point the camera at people doing mundane things. The subjects would often question why he was filming them and the response was always simply "oh, I'm just making a video". Occasionally the guy would elaborate further and it seemed the point was that people are captured and recorded on CCTV and other surveillance methods all the time, so why would they…
I agree that most reactions are not warranted. However, the context of the filming is quite different.
On one hand, you have (mostly) stationary cameras filming areas, and all the people in that area. Usually the cameras are not zoomed in, and ostensibly are not allowed to record audio in many jurisdictions. So you don't feel threatened because it's a universal thing and unmanned. Also, you assume the purpose is for property or personal protection.
On the other hand, you are being specifically targeted, including audio, by an actual human with a camera. Are they recording my credit card, pin, etc? It's reasonable to question what they are doing as it is unusual and could be a scam. The motive is unknown.
Context and details matter. My guess is they violated a law and/or got sued. It's much easier than most people realize. For example, if you record someone's conversation while their on the phone, you could be in violation of wire tap laws even if you didn't tamper with their communication (simply the act of recording).
