This was published on their own website, it is therefore biased toward a good perception of them. It doesn't seem to be a fair and independent review to help build an opinion.
In all those papers, there at least one member of the team in the author list, or a member of a partner organization (Intel, Lawrence Berkeley National Laboratory, etc). I wouldn't call them fair independent reviews of the language.
I would also argue that the large open source Julia packages are also great examples of Julia "in prod".
Just highlighting what I think is a significant con in a language with many pros!
