I've been on this website for many years, and have been following the privacy topic for more than a decade.
I never had the feeling in the past that HN visitors were especially pro-privacy. There were a few notable exceptions, but many more were the entrepreneur/hustler, "I don't care" or the "let the market sort it out" types.
In the past 1-2 years I guess there were several data leaks and privacy-related scandals and more and more people have had enough of these Monday to Friday advertisers on this Monday to Friday plane (of existance).
Hate would not be a wrong word to describe the feelings those people have towards the advertising industry.
Maybe the pendulum has swung back :)
