According to an article on the BBC news site, governmental increase in Internet filtering (structural censorship) has increased markedly.
“In five years we have gone from a couple of states doing state-mandated net filtering to 25,” said John Palfrey, at Harvard Law School.
Drawing on studies by the OpenNet Initiative, the article publishes the following list of countries in which ONI has found filtering.
Azerbaijan, Bahrain, Burma/Myanmar, China, Ethiopia, India, Iran, Jordan, Libya, Morocco, Oman, Pakistan, Saudi Arabia, Singapore, South Korea, Sudan, Syria, Tajikistan, Thailand, Tunisia, Turkmenistan, UAE, Uzbekistan, Vietnam and Yemen.
The article talks about a survey (no indication if it’s recent or not) that ONI did that studied 41 countries. I couldn’t find that survey on ONI’s website. That may be due to a website redesign combined with the fact I don’t want to spend all day rooting around on it.
