Big respect to Elbakyan. Couldnt listen all the presentation but I will soon, thanks for your efforts also. There are many attempts to stop sci-hub especially court decisions made in USA. The domain name/s constantly under attack by law enforcements. Other than some radical (or marginal lets say) groups there is no open support for sci-hub organization and what it does for science community. Its officially shown that even in academia of USA, students and colleagues prefer to use sci-hub even though they have access to free accounts for publications. (because sci-hub is faster)
Here is the link for the research of sci-hub usage: http://www.sciencemag.org/news/2016/04/whos-downloading-pirated-papers-everyone
On the other hand even though many academics use sci-hub, we see no support from them about this organization directly. An almost death silence there is. We also dont see any support or brave claims about the dark side of the scientific publication system currently going on all over the world.
On that manner I found your talk and related stuff pretty encouraging and hopefull for future...
