We've come a long way in 100 years
During WW1 German newspapers were widely available and read in London, albeit with a couple of days delay as they were mailed through neutral Holland. Nobody thought to suppress them, they were regarded as a useful window on the thinking of the German High Command (and who knows what the personal ads really meant?). I'd guess the reverse position applied.
During WW2 I don't think much effort was spent trying to suppress German 'news' in Britain, it was both predictable and somewhat amusing. The Germans did spend some effort to stop people from listening to Allied broadcasts but despite their best efforts (and some really severe penalties if you were caught) a lot of people did.
Now we're in the age of instant information it seems that we have to exercise total control over information. I've always thought of it as a sign of weakness. Here in the US although the usual cable providers dropped Russia Today (but who watches cable TV anyway?) the domain is readily accessible and the material it contains is -- predictably -- exactly what's said on the tin. The only thing really positive you could say about it is that its not clagged up with innumerable popups, adverts, bits of video and what-have-you -- its like an old school website from years ago.
This is the modern era. Information's going to leak out. The more you try to keep a lid on things the more people are going to suspect you're full of it.
