Amazon has not responded to requests for comment. Its terms of acceptable use include a ban on illegal activities (it's not yet clear whether Wikileaks has broken any laws) and content "that may be harmful to our users, operations, or reputation." It also prohibits using Amazon's servers "to violate the security or integrity of any network, computer or communications system," although Wikileaks obviously obtained the cables long before hopping on Amazon's servers.
The Electronic Frontier Foundation, a group that advocates for Internet freedom of speech by defending court cases, said the axing certainly doesn't violate the First Amendment. But it is, according to senior staff attorney Kevin Bankston, "disappointing."
"This certainly implicates First Amendment rights to the extent that web hosts may, based on direct or informal pressure, limit the materials the American public has a First Amendment right to access," Bankston told TPM.
Until Amazon.com explains fully why they've taken this action, you might think of doing your online business for the holidays elsewhere.
Pass the word.
