You seem to be so positive that this guy has committed an offence under UK law, so please tell me exactly what laws he has broken?
In the UK we have something called the CPS (Crown Prosecution Service). In their own words, "The role of the Service is to prosecute cases firmly, fairly and effectively when there is sufficient evidence to provide a realistic prospect of conviction and when it is in the public interest to do so."
The CPS investigated this case and decided that there was no case to answer to (or there was not a realistic prospect of a conviction under UK law). So if our Governmental prosecution service don't believe that he has broken a UK law (or believe there is no chance of conviction), why in hell is he being extradited?
The alleged crime took place in the UK, the content was not hosted in the US (or even on his site!) and if the CPS findings are anything to go by, he has not broken any UK laws. If the MPAA, RIAA etc. want to prosecute they should bring a civil action in a UK court, not bend a treaty designed to counter terrorism to protect their profits.
Believe it or not, it is not illegal to make money and not be an American.
