Understandable. Turkey ruling elites protecting country from possible chaos and hysteria amplified by social media. Twitter is still US based company and if asked would not turn back on US national security interests. As history shows, US tactic is to destabilize countries and make them weak, there is no better tool than social media platform like Twitter. To use Twitter right now and to take advantage of this horrible natural disaster and try to destabilize the country, is probably the easiest and best intelligence serviceman from Washington can do. This is just theory.
people using social media is not 'chaos and hysteria'. there are rescue teams on the ground , reporters etc many of whom are using twitter and certainly blockign a communication medium , any medium , in an destroyed area with devastated infrastructure under severe cold is an evil that Allah won't forgive.
I dare you to go to Turkey and help people or go fight with US or you're just another Erdogan-lover-bot. This government came this point with "US style libertarian economical and social movement" rubbish discourse and people only got "some Islamic totalitarian pressure and meaningless developments about building industry" from them which why so many people lying under the rubble this cold February night.
