"The UC Libraries do not endorse the use of Sci-Hub for article access.”30 As the UC Berkeley university librarian said in a published interview, “we are unequivocal: it is our understanding (though we are not attorneys!) that Sci-Hub is in violation of U.S. copyright law. We will not advise nor help anyone to use it" That is probably the best endorsing non-endorcement I have read. It never says they discourage SciHu…
At one point, that's a coward's stance. Alexandra Elbakyan's contribution to scientific research at this stage is probably higher than any university's library. Recognize that everyone uses it because none of the legal options are acceptable. Say it and urge a long overdue change in copyright laws. It is abnormal that Elbakyan is the outlaw and Elsevier the respectable institution here.
This non-endorsement endorsement achieves the same goals without the above liability.
