> on a sidenote, why arent authors and researchers publishing on scihub directly?

Many compsci/physics/math researchers already submit preprints (or post-prints even) of their papers to arXiv, which is public: https://arxiv.org/. I'm confused, is there a reason why they should they submit to Sci-Hub too?

They're not always quite the same, often arxiv have doesn't updates reflecting changes during the publication process (not including formatting). Can be annoying, the can be subtle differences and people aren't really careful about which versions they use or cite.
