It's hard to believe, but Microsoft's mainland China Web site scolds you if you type the words "freedom" or "democracy," or the phrase "human rights." The U.S. software company hosts a large Web site that provides free blogs to Chinese users, and software on the site monitors everything that is typed in. Offending words and phrases cause a window to pop up with a warning that the posting may be deleted if the user does not remove the "offending" words.
Microsoft says it has to adapt to local customs, but cooperating with a repressive government that prohibits free speech of any kind is a bit of stretch.
