The overwhelming majority of users on most social networking sites are lurkers. Those lurkers did not vote. I would assuming the majority of users do not even know about the changes or the blackout.
Lurkers also do not post content. But I imagine by this point most lurkers understand something is going on. Either because their favorite sub went dark, becasue it posts less content, or simply because news sites are making stories (while being posted back to reddit ofc).
