I can not see any right for any government to censur or cut off people from Internet, but it happens all the time. Are you sure that it can never happen in your country? I do not have any political opinion about Egypt, but I support the people of Egypt when they struggle for the freedom to express themselves.
3 February 2011 – Secretary-General Ban Ki-moon :
“Let me be absolutely clear. This is outrageous and totally unacceptable. It must stop now,” he said. “Respecting freedom of expression and assembly as well as information is a crucial and essential part of democratic values. I once again strongly urge the Egyptian authorities to listen to the voices of the people and immediately start real change.”
