Think it has anything to do with the HN crowd consisting disproportionately of the tiny minority of the workforce who make a living out of exactly the kind of behavior the GDPR wants to restrain?
And the best jokes where made by those who still have personal memories of the y2k scare. Did you remember to stockpile cash and food?
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 :)
For me it's very clear that while GDPR has many good things, it ís disasterous to some companies, which I really don't like and question myself whether it's worth it.
