As I apologize for the error, I'd also mention that the principle of charity is a thing for a reason. One may very usefully cite errors in published articles and request their correction without also suggesting their presence may be an attempt at deliberate deception. Certainly such things do occur, but we need not assume them, even provisionally, in the absence of any evidence that the error is anything other than an honest mistake. Such behavior when made a norm debases our discourse; such behavior when indulged even occasionally risks its normalization. I think the quality of discourse on Hacker News merits preservation and enhancement, rather than debasement. But perhaps you disagree.
