Living in a Western democracy doesn't necessarily mean that you can surf the web or use internet services freely, look at all those blocks for Bittorrent, the dozens of blocks for Nazi hosters, and especially the German court decision about YouPorn, which actually led to >2 million websites being invisible by Arcor customers; they can only be helped through proxys (though I don't think watching porn via proxys is good).

Most ISPs and indeed most places generally, even workplaces, don't block Wikipedia. "Argumentum ad YouPorn" won't really apply.
