I'm genuinely curious who you think would give you flak. Publishers? Your department faculty? The librarian at your university? Your peers? (reason I'm interested: I'm on the board of Sage and have a board meeting tomorrow where I hope we'll be discussing sci-hub)
SAGE Publications' busts of the peer review and citation ring back in 2014 was great work. Might it be possible for you to expand on SAGE's position of Sci-Hub?
Sage is in a particularly interesting position because we serve so much of the humanities and social sciences (HSS). In STM you can make the legit argument that all published research should be open access and the cost of that should come out of the same funding that funded the research (ie NIH or private funding agencies). But in the social sciences there isn't the same funding picture.
So even if we decided we were going to be super ambitious and flip all of our journals tomorrow to author-pays OA, it's hard to imagine that working in HSS. What would end up happening? Hard to say, but my guess is that a lot of our journals would collapse for lack of submissions and the vast majority of the content would go to our competitors' paywall journals. And remember that a lot of our journals are academic society journals and the societies rely on the journal revenue to operate. So it would also meant the implosion of significant societies that currently serve their members (well, in reality it would just mean they'd migrate their journals to another paywall publisher).
The whole thing is super messy and complicated. The competing interests of societies, academics, universities, funding bodies, tenure committees, etc all make it a big complicated mess (particularly when focusing on HSS). I wish we could have some of these debates in forums like HN in an intelligent way, but that's pretty hard to do given how quickly the pitchforks come out.
