Al Jazeera the threat

"Many Iraqis remain weary of having their names published" MacFarquhar puts this quote in parentheses for a reason. IF Al-Jazeera is such a popular information outlet for Iraqis, why are so many resistant to allowing their names to be used? Is there a sense of fear for going against this network's views and information among the citizens of Iraq? If i believed in a network and its opinions, there would be no problem using my name to support them; the same being as if I were a dissender of the network. This doesn't seem to be the case in Iraq, where anonymity rules regardless of personal opinion.
