To me this is like the post office banned people from sending letters
It is the Police job to pursue criminals and whether I write something in a letter or I share CD I have bought, it should be the police that police this.
I think it is just fundamentally wrong that the a broadband provider gets involved with policing what people use their broadband connection for.
I don't have an issue with the police finding and prosecuting criminals (file sharing et al) but I do not want my post office to read my letters and then make a decision whether I should be allowed to send any further letters.
That is the police job
