Excepts the internet blackout has nothing to do with censorship at all. This is just Iran protecting itself from cyber attacks, if they had kept Internet running, they would have been completely pwned.
It is true that shutting off your Internet prevents cyber-attacks, but imagine if it happened in the USA: it would effectively shut down much of our commerce and everyday living activities. In the West, Internet access is becoming more of an essential utility than the icing on the cake, or a recreational forum for malcontents and ne'er-do-wells. Or perhaps it's both at once.

All I know is, if I was at war with the USA, I would definitely cut the internet in my country. Not doing it is like being at war with a big maritime power, and not protecting your coastline.
Can you elaborate how such thing plays out?
