You could have just pointed out the Samsung product.

"confidently" doesn't assume intent. "misinformation" doesn't assume intent.
But it's also a more complicated point than you're giving credit for. That comment directly addresses lack of knowledge and accuses people of negligence, not lying. I do not parse it as an accusation of intent, and given the followup here I don't think izacus sees it as an accusation of intent either: https://news.ycombinator.com/item?id=42669379
But even if it is an accusation of intent the only accusation is deciding to be reckless. Which seems pretty justified to me.
(And there is a flagged comment that I have a big thing to say if you make me, but I'd rather we just ignore that comment as a separate thing.)
