Nix's definition of "reproducible" is different from what the author says they want though. Nix gives you a similar system from a given config, when it works, where the author wants bitwise identical results (even when compiled at a much later point in time and on a different machine, which you can't accomplish just from caching (unless the caches are remotely hosted)).
The reason they don't like Nix should be obvious; it blatantly and vocally doesn't even try to do the thing the authors want. It'd be just as relevant to bring up Gentoo or something -- another fine project, like Nix, but not especially helpful for the stated problem, and so obviously so that it shouldn't be worth paying lip service to in the article.
