As they're messing with DNS, you'll still be connecting to their evil version of YouTube through your SSH tunnel. In Firefox this behaviour can be changed by toggling network.proxy.socks_remote_dns in about:config.
Of course, setting up an actual tunnel (i.e. on a lower network layer) would be better but that's a bit more complicated to do.
sshuttle --dns -v -r username@servername 0/0

It's not like our government is blocking anything (there were rumors it was blocking Facebook in 2011, but it wasn't true as I was able to log in without any issue. It was just slow, but it's not like we have the fastest internet here).
But it's nice to know. Thanks for the clarification.
Plus how can you tell it isn't the actual Facebook if everything is there, status, etc, comments, pictures. I can chat with other users, send messages, etc.
