I agree with you on this, but I'm thinking more as a matter of perspective. HN is just not a place where I expect to see vicious, anti-tech backlash given the demographics.
I think the demographics are changing, more so in higher visibility articles, but generally too.
I think the best part about HN has always been the comments discipline. People generally only respond when they have some knowledge (not just “I watched a YouTube video).
That has faded sadly.
