Killing the messenger
I'm not surprised the American government would like to see Wikileaks shut down. What I'm surprised at is how easily non-government actors fall into line to help out.
Fundamentally, Wikileaks is a news gathering organization, and yes, a quarter million classified documents is news. Wikileaks didn't break confidentiality by publishing the documents, because they aren't required to hold these documents in confidence. Sure, the US government of the time wanted to keep the New York Times and Washington Post from publishing the Pentagon Papers, too, but life is filled with disappointments.
Now, as private organizations, Amazon and PayPal are under no obligation to help Wikileaks work, but I don't think it's unreasonable to ask what principle Wikileaks has violated to earn this sort of exceptional scrutiny. I can't think of one, myself - they received confidential documents, and they're publishing them.
Anyway, they can continue to be found here. Twitter has proved extremely useful, as their opponents try to play hide and seek with the site, but since this is an IP rather than domain name, it should hold solid.
As for my title, well, some take it more literally than others. Can you still collect a paycheck from the University of Calgary after advocating the murder of a newsman? Apparently so.
