I'm wondering about this too. What could be the possible other reason for the papers not being downloaded? Boring titles? Preprints easily available? Open access?

Is it possible that the articles really were not available, as they used the data from sep-2015 to feb-2016, early version of SciHub?

That's within the realm of possibilities but sure doesn't sound like the case the way they described their methodology. That would have required a catalog of available papers on Sci-Hub too, but the dataset they used only contained download logs, so they couldn't have known whether a zero-download paper was available or not (unless I misunderstood what the first dataset is about).
