Row over United Kingdom internet safety filters

I've written before on the dialogue of the deaf between politicians and the internet industry over child internet safety - and now the relationship seems to be getting even worse. A letter sent to the UK's four leading ISPs from the government has made them very cross indeed. So cross that someone in the industry has passed it to me - you can read it in full below.

The letter comes from the Department for Education but it sets out a list of demands from Downing Street, with the stated aim of allowing the prime minister to make an announcement shortly. The companies are asked, among other things, for a commitment to fund an "awareness campaign" for parents. They're not particularly happy about promising cash for what the letter concedes is an "unknown campaign" but it's the next item on the menu which is the source of most of their anger.
