No wrong could possibly ever be done by the end user. It's always PayPal's fault. Ridiculous!
Half of the things that wikileaks does is borderline illegal. I'm not saying that the things they expose don't, but there might be better means of doing it. I have no idea if Wikileaks has broken the ToS but it's perfectly within PayPal's rights to freeze an account for fraud.
9 times out of 10, it's an automatic restriction put in place by various fraud rules. It happens and is also why PayPal doesn't lose their ass to fraud.
PayPal for the record of course wants to become a bank. But it's a long slow process to do so. Stop acting like PayPal is trying to skirt the law by not being a US bank. It's more of a hassle sometimes to not be and certainly costs more in the end.
