This is, somewhat ironically, the most well-known HN comment outside of HN.
But such is normal with normies providing startup critiques, if you just look at every announcement and say "this will fail", you'd be right 99% of the time.
So nothing really has changed in this community's vibes.
I mean - just looked at this downvoted comment essentially saying the same thing - https://news.ycombinator.com/item?id=49119464. And also the intensity of the replies.
