Are xHamster users going to be contacting their reps to complain that they can no longer access it? That's another situation that seems unlikely to me.
You're still missing the point. Users who know little to nothing about the law NC passed will be made aware of the issue. Some of those people will take action against the lawmakers and/or people that support the law. Overall awareness of the issue will rise and hopefully cause a real discussion.
No, they're going to contact their reps to complain about the anti-lgbt law that they're suddenly aware of.
No. They'll switch to YouPorn and the others that will be happy to have xHamster's clicks. And if they all follow xHamster's lead, they'll learn how to use VPNs.
Then the whole thing will burn itself out from outrage fatigue and be dropped.
