The evidence I present is that I have never seen someone complain about someone else filming in public. I’m not sure that the articles position on HN says anything about the majority opinion on a topic, only that it’s of interest.
I have practiced "street photography" for years, where I purposefully take pictures of people on the street. Sometimes people ask what I'm doing, I tell them, and they say "cool can I see the pictures"? Sometimes I send them a file or whatever. No one's gotten all out of sorts over it.
