Big Brother

Ok, so it is not as bad as it seems but, I was just reading where Google refused to release the names of people who were querying for pornography to the US Justice department. Yeah, good for Google and for children everywhere. But at the end of the article they mention, "Three of Google's competitors in internet search technology - AOL, Yahoo and MSN - have complied with subpoenas in the case." Does that mean that all three of these companies handed over any and all info? Here is an interesting point for research. But then again, do I really want to know?
