Yes, pg doesn't make a point of reiterating it every year. Is the community really different? I've been around for some time and I haven't noticed. dang is a mod/admin. Here he is repeating it again a year and a half ago:

So we have a community manager repeatedly saying "yes, this is intended", and a random user saying it's not. The downvote button on articles is a completely separate issue.
I do think HN is much bigger now. There's less discussion on philosophy of startups in general. PG himself rarely blogs about it any more. It also seems like political topics get more frequently introduced on the front page. Also there's frequent toxicity and negativity about certain technologies which do warrant intellectual discussion, but get dog piled by naysayers. Maybe that's always been there and it's my imagination but it does seem like some of the "hacker ethos" has faded.
And for example, unlike Reddit, you can't downvote items on the main page, just comments.
I'd be curious to hear an updated discussion on this, but I've seen salient points being downvoted into obscurity simply because it accrued a lot of downvotes, and I'll find myself upvoting posts I disagree with just to keep the post alive.
