I take your point about the legal precedence, but the more commentary you read on the UK situation, the more clear it is that telcos and isp's have been dragged kicking and screaming to this. In fact, going on what's been written in the various articles, it's more that they've seen the writing on the wall, and voluntarily adopting a more anti-piracy approach is cheaper than fighting cases in court, and better than being regulated by new laws.
