If federation takes off even the government won't really be able to gently censor it, though. They might stomp and complain but short of breaking down a server room door there's little they can do, and the only things that get that treatment right now in the West are child porn and stolen credit card numbers.

They could basically close off the internet like Cuba or to a much lesser degree China, but closed internets/intranets tend to suck, and then they're in the awkward position of either rubber-stamping adult websites or banning them, which straight up won't fly anytime soon.
