They already have the weaponry. They have captured the content people need to advance science and learning. That's already lost, we can't re-fight that battle. The choice now is to either use SciHub to access that content by other means, or voluntarily avoid doing this - thus granting them the spoils of the victory, and hope to maybe, maybe have some content free in the next one. I don't see how not voluntarily granting them the spoils makes anything worse for me - the legal system is always on their site, and that won't change in my lifetime. So it's either no access to papers for me, and hoping that maybe my grandkids will have some - or SciHub.
