If you want me to offer even "grudging support" of Jim Gamble, I'm going to have to see something more convincing than his "diplomatic language".
Remember that he was the one who, only a few months ago, said that ISPs should waive the costs of "assisting investigations" when children are involved and was roundly criticised by ISPs, especially the smaller ones, for this. Then, a couple of days ago, CEOP declared that "the vast majority of paedophiles exchange images via P2P".
Now, suddenly, he changes his tune and decides that "well, maybe small ISPs shouldn't have to be forced to adopt filtration" which sounds to me more like he'd realised that there was no way that such a thing could get pushed through without a lot of resistance that might then backfire as larger ISPs start saying "hang on, if they don't have to filter and since only 7.5% of this stuff comes from commercial websites and most of it is going via P2P, why should we be wasting our money on it either?"
Don't forget, also, that Gamble was a major mover behind Operation Ore, and that house of cards is looking extremely shaky with the Jim Bates/ Chief Constable Colin Port fiasco and innocent victims of credit card fraud being effectively forced to plead guilty to avoid a court case which, even if they won, would have ruined their lives.
Additionally CEOP wanted to censor Second Life just in case someone used underage avatars to "groom" children and they're also one of the groups that pushed for the clauses in the Coroners and Justice Bill to make pornographic cartoons of "chidren" illegal.
Now IMO Gamble is thinking that he's pissed off a few too many people and he's hoping that a bit of "diplomatic language" might smooth things over before too many questions are being asked about the power that he and CEOP have arrogated unto themselves.
Oh and your last paragraph reads like "Won't Graham Marsden Think Of The Children!", so please excuse me if I ignore it (and your title line) with the contempt it deserves.
