Because They are afraid, very afraid...
How to explain such a clearly ridiculous ruling? Because career politicians and bureaucrats (who consider themselves, incorrectly, The Government) are terrified of the Internet and its ramifications. They see it as a zero-sum-game, that empowering people with access to information and low-cost, large-scale means of communication will diminish their power.And in the traditional sense, they are correct. So do not underestimate the means to which they will resort to cling to their old power model. (see Mubarak, Assad, et al)
