Anonymous did not ignore anything. I just read through the emails. Anon. CLEARLY wanted money. The demand was $50K immediate payment to something called Liberty Reserve.
FBI/Sym was attempting to get the payment broken into monthly payments and made into pretty much anything BUT Liberty reserve.
There was some discussion about whether FBI/Sym can trust Anon to not publish after they received the money. The response that Anon had was that 'You have to trust us. If we were bad guys we would have already published.'.
At no point in those emails are there any motivations discussed EXCEPT a payment for not disclosing the files.
You can argue the email is a fabrication.
You can argue that it isn't really Anon behind this.
You can argue the files released so far are outdated and a joke.
You can even argue that this is all a clever ruse on Symantecs part to get people to drop PCanywhere 2007 for the latest release.
But to argue that the entity Anon in that email is doing anything other then extortion is absolute bullshit.
