This is indeed a curious turn of events.
The internet search engine Google is resisting efforts by the US Department of Justice to force it to hand over data about what people are looking for. Google was asked for information on the types of query submitted over a week, and the websites included in its index. The department wants the data to try to show in court it has the right approach in enforcing an online pornography law. It says the order will not violate personal privacy, but Google says it is too broad and threatens trade secrets.
Yahoo and MSN meanwhile, either admitted or tacitly admitted complying. What is Google protecting? Is it trade secrets?
Update: Dan Drezner adds his weighty two cents to the debate.
