Google has been the target of a number of privacy critics, most likely because of the huge amount of information it is privy to and the lack of transparency about how much of it is kept in a personally identifiable state and for how long. An editorial in today's New York Times calls for a "privacy upgrade" at Google.
Here's a snippet:
What Google Should Roll Out Next: A Privacy Upgrade - New York Times:
The government can gain access to Google's data storehouse simply by presenting a valid warrant or subpoena. Under the Patriot Act, Google may not be able to tell users when it hands over their searches or e-mail messages. If the federal government announced plans to directly collect the sort of data Google does, there would be an uproar - in fact there was in 2003, when the Pentagon announced its Total Information Awareness program, which was quickly shut down.
Google says it needs the data it keeps to improve its technology, but it is doubtful it needs so much personally identifiable information. Of course, this sort of data is enormously valuable for marketing. The whole idea of "Don't be evil," though, is resisting lucrative business opportunities when they are wrong. Google should develop an overarching privacy theory that is as bold as its mission to make the world's information accessible - one that can become a model for the online world. Google is not necessarily worse than other Internet companies when it comes to privacy. But it should be doing better.
