[...] In what universe, besides the one of a sentiment-analysis-algorithm, would that be considered a "negative" comment? To clarify, they said they manually classified the top comment instead of leaving it to the judgement of the algorithm: ", we manually categorized the top comment for each thread." As for why their human eyes judged it as "negative", I'd speculate it was phrases such as "The only problem is", "That's gonna be the problem.", "your USB comparison fails" So yes, the top comment's criticism is constructive, but at the same time, it can also be subjectively classified as "negative." The positive back pat at the end of the post was not about the product itself but for the accomplishment of launching something. (You could say it's the attaboy "trophy for participating" consolation prize to soften the previous paragraph's criticism.)
