. "Sci-Hub leaves the false impression that OA requires copyright infringement, or that OA must be unlawful....Anti-OA publishers argued for years that OA, or OA policies, intrinsically violated copyright. They were wrong, and in my opinion most of them knew it. But it took years for widespread public correction to have an effect. I was one of many who took part in that effort....One result of that communal effort is that publishers have gradually stopped raising that false objection, and newcomers have gradually stopped making that false assumption. The risk of unlawful OA services is that they could trigger a new wave of false assumptions about (0) the lawfulness of OA, (0) the wide range of lawful options for researchers to make their work OA, and (0) the importance of persuading researchers to make one of those lawful choices."
