Your being a bit presumptuous there, in most Western countries they'd be able to block VK and other non-local sites without protests in the streets, and if they occured you'd see a significant portion of the country (esp. in the US) hoping for the police to come in and crush said protest.

Depending on the subject, the protest can be crushed, hence why most public spaces in the US have been bricked over for easy protest breakup.
