I am vaguely concerned about parts of this post being on less wrong—I’m don’t think we should be a place that openly advocates for illegal actions without extensive justification? Both for legal liability reasons and for philosophical ones.
I’ve tried to provide a legitimate alternative to every piratical source I’ve mentioned—if others concur with you I’ll reduce the discussion of piracy sites to just a brief gloss of sci-hub.
As a site admin, I don’t think I have any concerns about the legal reasons. I obviously feel philosophically good about sci-hub, I don’t know the others so well (though I’d be a bit surprised if one of them was bad enough to remove).
