NASA ADS (link is ugly and is at the arxiv page) lists three citations. Of those, 1608.02882 (and also 1608.07136v1 which is not listed there) are a straight attempt at rebuttal, by the same author, the other two I didn't read yet. As far as I understand, which is not much, that attempt was found not well founded. At this point I can only suggest somehow searching for discussions that appeared back then in 2016. I don't think there was any formal (as in a published article) rebuttal of this rebuttal, only a summary in Gorkavyi's blog, which is in Russian and too complex for me to translate[1] I'd wait for more papers from the original authors, in the hope that they would generate more discussion. One has to take the academia's inertia into account - someone who wrote a couple of dozen papers on dark stuff is understandably reluctant to even mention and thus acknowledge a competing hypothesis. 1. https://don-beaver.livejournal.com/176937.html https://don-beaver.livejournal.com/176937.html
