Not that I'm some paragon when it comes to critical thinking exactly, but if there any sort of proof or evidence of Anthropic "silencing negativity"? Wouldn't surprise me, but also haven't seen anything conclusive about it either, so spreading that they are as fact, is ironically FUD itself.

Name a startup that isn’t trying to downplay, scrub, or otherwise silence negative press.

When they say "doing the opposite" they are referring to Anthropic's hyperbolic marketing strategy.

Though, I don't think that justifies spreading FUD in the opposite direction. I also don't think the comment the GP was replying to contains FUD.
