That's not close to true, but even if it were, it doesn't make it ok for you to break the site guidelines. Commenters here need to stick to those regardless of what anyone else is doing. Otherwise, we just end up in a downward spiral, since everyone always feels like the other side started it and did worse.
HN has fallen. It's infested with operatives and shills. Waving the site guidelines at me for offering a modicum of balance is the wrong way. Either ban all political commentary or let 'em cook. Putting me in a timeout for mild snark? It wasn't always like this.
HN's standards haven't changed. I think it's just that everyone underestimates their own provocations ("mild snark") and overestimates the provocations of others. This leads to an "objects in the mirror are larger than they appear" kind of effect - https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que....
"Infested with operatives and shills" is a feeling that a lot of internet users have when they encounter views that are different from their own. It feels like these can't possibly be in good faith, so they must be "operatives and shills". But there is a much simpler explanation: the range of differences between people is just a lot larger than one expects it to be. I've written a lot about this over the years—here's one example, with links to others: https://news.ycombinator.com/item?id=35932851.
This is why the HN guidelines ask people "Please don't post insinuations about astroturfing, shilling, bots, brigading, foreign agents and the like. It degrades discussion and is usually mistaken. If you're worried about abuse, email hn@ycombinator.com and we'll look at the data."
