I completely agree with you, and what i wrote was in haste, essentially, what i wanted to say, was that an individual running searxng does not provide the anonymity benefits you would get by using some public instance, but it it still better because you are not directly using google or whatever website, and now searxng kinda acts like a browser between you and them, which does limited conversation - there aren’t any js based fingerprinting. I also use searxng locally, i cant stand the constant rate limiting of public servers, or sometimes only a few engines are blocked, and variation in result quality is unacceptable to me. I just wanted to add that bit for transparency,
I agree, those are just 2 examples of people doing fact finding, idea is someone will post something, and other lemmings will do what people in the video did
