A paper published in Nature is being criticized as "too neutral" for pointing out that the evidence is inconclusive.

My comment is getting heavily downvoted, despite being properly sourced. No counter-argument or evidence is presented.

Why? Does nobody care to explain themselves?

Maybe your negative tone or the low information density. I guess just dropping links is frowned upon. You could have written a short summary or at least paste the TLDR from these papers and then link to the sources.
