This happens to almost every post that’s somewhat negative about Tesla. They mysteriously disappear from the front page within minutes even after getting a lot of engagement.
I’m pretty sure some nefarious flagging is happening and I hope dang takes a look at it.
I usually flag posts like these after a scan through the comments, as even though the article is tech related, the comments on this type of topic are usually uninsightful, 90% of the time just being typical political/social echo chamber warfare, an excuse for people to post low quality comments shitting on the persona non grata, in this case, Elon. These types of topics on HN usually accomplish nothing other than increasing the hate in the world. If the comments don't follow that pattern I don't flag. But they almost always do.
