IMO the argumentation of PayPal is pathetic. They did not even have the balls to admit that they just wanted to stay out of trouble and trying to shift the blame to someone else.
On the other hand, from what I know they don't have much reputation left anyway, so it's a bit of a moot point.
That is the real problem here. Even though the SD can't, or hasn't yet figured out how to charge Wikileaks with a criminal offense, they wield their power as a bullying tactic to get what they want.
"Comply, or else ..." is an abuse of power and is exactly what wikileaks was set up to expose in the first place. Even if the SD does succeed in trouncing wikileaks into oblivion, that very act serves to expose how corrupt governments can be.
Not telling us to fire them of course - just a 'friendly briefing' of their 'security concerns'
