I think the issue is that you are saying things are "normal" without addressing whether or not they are right and good.

I would probably agree with you that it's normal for a country at war to want to control information flow. But that's absolutely a bad thing! Obviously not all "information" is created equal: some of it is high-quality and objective, and some of it is lies (and everything in between). I don't trust pretty much any government entity to be objective about these sorts of bans, though. The ultimate consequence of these sorts of things is a poorly-informed, propagandized public.
