The Indian government and security forces took a decade before they realized that email is not private and Windows has more holes than a sieve. So when they warn people that Facebook usage could expose relationships and connections and pose other security threats they have not even realized that it is not Facebook alone but also Twitter, Whatsapp and a whole lot of other Social apps that mine your personality, contacts and data.
I think Indians are far far away from understanding the security implications of a connected world and on average, government agencies and the armed forces IMO are ten years behind the average schoolboy geek
What I fear is that everyone will believe that Facebook is a problem but not Twitter or Whatsapp and make all the security mistakes on other applications that were sought to be prevented by issuing a Facebook warning. My other worry is that those who issue the warning are often types who trust Microsoft Windows. I am suspicious of the latter group. Too often I find that bank security software in India is built around M$windows and Internet Explorer. For a country calling itself an IT power - the level of awareness is frightening and pathetic.
