Laurie Penny The Guardian, Friday 3 January 2014 "The worst thing about the porn filter, though, is not that it accidentally blocks a lot of useful information but that it blocks information at all. With minimal argument, a Conservative-led government has given private firms permission to decide what websites we may and may not access. This sets a precedent for state censorship on an enormous scale – all outsourced to the private sector, of course, so that the coalition does not have to hold up its hands to direct responsibility for shutting down freedom of speech." - BT's opt-in filtering system , covers "sites with information about illegal manipulation of electronic devices [and] distribution of software"
