FWIW, I remember that result (i.e. the paper by Ng) being moderately prominent among (mostly negative-leaning) people I discussed wild animal welfare with in 2016. However, I think they treated it as one of several lines of evidence pointing in the same direction, and so I doubt that learning about this result being wrong would have by itself have changed anyone’s bottom line in an immediately action-guiding way. (I do think it would have made people somewhat less confident that many wild animals’ lives are net bad.)
