That's not accurate. HN is an American website hosted on American servers catering to everybody. The only prerequisite is intellectual curiosity: https://news.ycombinator.com/newsguidelines.html
Intellectual curiosity exists everywhere, HN's userbase is 50% outside the US, and at least 90% outside of Silicon Valley. That's important for people to understand.
Meanwhile, I've tried to see if this bit of info can be added to the HN repo maintained by Max Wolf.
