I don't think this dismissal is quite fair, especially regarding this work being unscientific or having negative value to humanity! The paper described here isn't survey-based; it actually seems very quantitative compared to other psych papers (they collected audio for "150,000 recordings" and computationally analyzed the data; the survey part sounds more like diary data collection). But even if this was entirely survey-based, it wouldn't necessarily be useless. I do think that it would be better to cover trends in the literature instead of individual studies, but in this case it seems the paper has important implications for sentiment analysis and computational social science in general. I currently hope conferences don't go away!
