I m all for blocking those US social media sites in China, giving the control of your social media to foreign hands is like handing a gun to them to shoot you. if being used against you, that can cause havoc in your society. India should also take note, now you enjoy good relations with the west, facebook, twitter, youtube.. don't seem to hurt you much, but once you fall out with the west, the damage they cost your country can be imaginably massive.
