There is no such thing as "Cameron's filter" though. David Cameron is a politician whose party has a "think of the children" policy and has pledged to "get tough" and "crack down" on the availability of naughty material online.
The filtering "policy", if you can even call it that, is basically just to urge ISPs to implement content filters of some kind. Not mandatory - not all ISPs have chosen to play along, but the big ones have due to the risk of reputational damage if not. Customers of ISPs with such filtering get the choice either to allow or disallow the content that their ISP's chosen filtering solution thinks may be unacceptable. Some ISPs offer more comprehensive and flexible filters than others. E.g. Some will just block anything "not for kids and nice families", others have a wide range of categories and options - just like corporate filters and technologies like WebSense offer. (e.g. Only block porn, allow sexual health, block humour and social networking sites, allow file sharing, etc etc etc)
There is NO "Government" filter. There is only a POLICY. Just a policy - barely even that. Certainly no legislation or law. Just a statement of intent, that "we think people should do this" and that's all.
Fight censorship, absolutely. But be right about what you're fighting. Opponents arguing against this policy using outlandish and wrong claims just blow holes in the credibility of the "no" camp, which will just make it all the harder to argue the case if/when genuine, non-optional, state-backed censorship DOES come to tea.
Eh, we agree with each other. I've made similar arguments on HN in the past.
But this newer lever of filtering is called camerons filter because he's been heavily pushing it, and he has said that more needs to be done on top of that filtering.
I can't buy into a slippery slope argument, because I don't really think this is going to happen. And if it does, we should fight it.
Gov said it's not enough and pushing for wider coverage of the filters.
Are they? I've not seen evidence of this anywhere.
