I agree with your sentiment though - the internet _should_ be free.
Content shouldn't be blocked, the Internet should be free and open. However without letting people know what's happening they will not complain.
Of course what the browser should display is:
451: The Right Honourable Claire Perry MP has deemed that you shouldn't be able to look at this site.
IMHO, she is ignorant(1) and irrational(1), and there for scared witless of the internet, so she seeks to control it. I don't think she knows how wrong she is, there for I don't see her as evil, as such. However, it does seem our vote whore of a Prime Minister listens to her every word, hence the attempts to block porn and make people opt in to avoid the blocks, since her position ties in to an awful lot of right wing voters, who are equally, if not more, ignorant and irrational. They are the kind of people who genuinely believed Rock and Roll was the work of the devil, and that black people are a different species.
(1)I use these words for their real meaning and not the insult, judgement, or political value. I honestly think many people literally do not understand the technical issues, and act illogically as a result. I believe this is a lot to do with the traditional media, who politicians rely on, issuing scare stories about the internet because their business were and still are threatened by it. My "evil" in this is those who spread the lies, ie, the media. I hate to admit this, but in many ways I see the likes of Clair Perry as well intentioned victims and mules of the media.
