Should they or shouldn't they... autocensor themselves in order to stay up and running in countries that have different censorship rules ? A lot has been written about this (check out ethical corporation with links to amnesty etc...), and a lot of criticism has been directed at Google, Yahoo! and Microsoft. It is not an easy question to answer. A bit like privacy rights, they are different in different cultures. So when in Rome... I guess they did what they had to do.
