Repressive governments widen stifling techniques
Repressive governments no longer limit themselves simply to blocking access to websites they want to keep from their citizens. Increasingly, experts on internet censorship say, they are turning to a range of other techniques, from methods developed for “cyber-warfare” to the filtering-out of specific content deemed undesirable.
