The Swedish government is not known to protect its citizens very well. Recently, the Justice Department and the security police caused the shut-down of a political party's website because of a cartoon of Muhammed looking at himself in the mirror with a blindfold, with the accompanying text "self-censorship". That is just about the tolererance level the Swedish government has.
Sweden is also notorious for being a leader in the EU implementing repressive laws in general and on the Internet in particular. The recent EU Data Directive is essentially one man's work, Swedish Justice minister Thomas Bodstrom, a former football player who smoked dope, somehow managed to become a lawyer and then to everybody's surprise was turned into minister of justice, on which position he has drafted more laws than anyone in history and effectively flushed personal integirty down the toilet. The directive, since long before in effect in Sweden, makes it mandatory for ISP:s to save customers' internet traffic data for at least two years. Other repressive measures in Sweden include a law against writing about other persons without their express permission unless being a journalist.
Sweden has also joined the ranks of the filter regimes, using DNS spoofing and other sabotages to the infrastructure to redirect pornsurfers looking for kiddie porn to a government website. It is not by law, but by cooperation with all the larger ISP:s (under threat of legislation).
You might also wonder why Sweden has not voiced concern over Chinese journalists being jailed in China. Well, that is because Sweden has had its own Shi Tao since the 70s, Jan Guillou (and Peter Bratt), who investigated and reported about an illegal spy organisation (Inormation Bureau) and subsequently was put to jail for espionage.
One might have the impression that Sweden is a free and modern welfare state, but those days are since long gone. Today's Sweden is the leading oppressor in Europe, with no-tolerance laws on everything from gambling to prostitution and drugs. The Swedish government sees the Internet mostly as an outlet for hate speech, porn and illegal downloading, and if they would decide to shut down the Pirate Bay during a lunch break, it would be done in a matter of minutes by a simple phone call.
