Elsevier and others can go something themselves. Their behavior over the last two decades has been little more than reprehensible rent-seeking. Whatever goodwill they had disappeared as they sapped with increasing ruthlessness the dollars of students and non-profits. See, e.g., one of many such figures: http://www.lib.washington.edu/scholpub/images/economics_grap... It is absurd and dishonest to call Sci-Hub "piracy"…
I am with you, since pretty much any scientist would love to be cited by another's research, any scientist will send you a copy of their paper if you ask them for it. And since the creator of the work is willing to give it away to you for free, it cannot possibly be "piracy".
My client (who will remain unnamed) insists that I advocate for his position: Just as a work-for-hire belongs to the party who paid the creator, surely it matters that the creator signed a contract with a publisher giving up rights to distribute the work in return for invaluable services? Are you implying that the creator retains some sort of "moral right" to distribute copies of the work to whomever despite the explicit stipulations of the contract?
