I noticed the URL was updated for this post. Previously it linked to asahilinux.org which showed an anti-HN manifesto from the HN referral. Curious as I haven’t seen this before. Seems it has been covered by previous commenters: https://news.ycombinator.com/item?id=36227103
The URL wasn't updated. You're thinking of https://news.ycombinator.com/item?id=41799011, which was a separate post.
How can the site even detect where a user is coming from? Browsers leaking this information seems like a huge privacy issue to me.
It's almost as bad as jzw's website: https://cdn.jwz.org/images/2016/hn.png (nsfw)
