There's an article in the Times Higher from Oct 28th about how some countries restrict internet access in ways which affect HE institutions among others. The articles mentions, for example, that in Belarus, university staff are required to monitor students' use of web sites. Zimbabwean academics have been affected (though not specifically targeted for) internet and email restrictions. Chinese academics have to be careful about what they say and what they look at on the web. And so on.
I'm sure all the examples given are true, but the phrase in the article which caught my eye was this one:-
Academics in most countries take the web for granted. The internet's vast array of information is a natural habitat they are free to explore.
So the assumption underlying the article is that in the UK and other "civilised" countries, academics enjoy complete freedom, and this contrasts sharply with more oppressive regimes. But is this premise really true? Here's a page about web filtering at the University of Aberdeen for example. Here's a similar page from Glasgow Caledonian university. The majority view at UK universities, I think, is still that blocking access to some web sites is undesirable, but it's by no means the inconceivable undertaking that this article appears to suggest; many UK universities, including this one, have at various times considered the possibility, but come down on the side of academic freedom or technical unworkability. Never say never.
