They're pointing out that anecdotally, Deno seems to be a non-player right now. Which is pretty spot on: it's still very new, and hasn't found a critical application yet (e.g. would Node have taken off the way it did without Express? Probably not). So right now, it's an enthusiast's plaything, even if the architectural principles are much cleaner (wrt modern JS) than Node can ever become - without a rewrite so drastic it'll split the Node community like Perl 5/6 or Python 2/3, at least.
