Amazon got WikiLeaks. Google got The Innocence of Muslims.
Each company hosted the controversial content, on Amazon Web Services and YouTube respectively. Both of these are self-service platforms. Members of the public upload what they wish and are legally responsible for it. The companies neither vet nor admit any legal responsibility for the content. Both companies have terms-of-use clauses that prohibit interfering with IT (flood attacks, etc) and copyright violations. Amazon also has a catch-all “no content that might reflect badly on us” clause, and YouTube doesn’t.
When the stories broke out, Amazon quickly kicked WikiLeaks off their servers. This was not motivated by a legal or political request – Amazon just decided to do so. See their statement here: http://aws.amazon.com/message/65348/ So far, Google is still hosting the anti-Islam video but is blocking it in the Middle East. The White House asked Google to consider taking it down, but Google declined.
No-one has been harmed by WikiLeaks as far as I know, other than the source of the leak who is detained in the US. There was grave risk that people in the spy services, their informants, and perhaps well-meaning dissidents might be imprisoned, tortured, or killed as a result of being identified. The WikiLeaks team made a diligent effort to minimize this risk by redacting, and as far as I know there were no confirmed or officially claimed victims. Of course given the secrecy we may never know. So far, several people have been killed in Libya as a result of anger at the anti-Islam film, including the US ambassador, and there have been riots elsewhere.
