No government operatives have permissions of any kind on HN. We don't know any government operatives nor have we ever heard from any*. I assume HN is much too small a fish for them to fry. You're overestimating HN's real-world impact by a long shot (but underestimating page views btw! it's more like 8M hits a day - maybe 10M if you include the API).

Plenty of posts on HN are critical of megacorps, government, status quos, and/or media narratives. You might be closer to the mark with your phrase "sowing resentment", though—that sounds like ideological battle, flamewar, and other low-quality internet noise, and those are indeed things we don't want here. Not because we're trying to preserve status quos—we aren't—but because we're trying to run a forum for curious conversation, and resentful rallying poisons that utterly.

* other than from law enforcement on rare occasions - maybe once every 2-3 years, if that - in connection with some investigation or other. Never anything political or ideological though.
