You misinterpreted the CNSNews.com article. You used the term voluntary but the incidents referred to in it are involuntary demands. That is, they represent legal process, such as a search warrant, a (d) order or grand jury subpoena for non-content logs, etc. If Google gets a valid court order, it is required by law to involuntarily comply. Similarly, if the cops show up at 6am at your home with a valid search warrant, you're required to involuntarily let them in and conduct their search. Also the good folks at CNSNews.com (published by the conservative advocacy group Media Research Center) would probably not be my first choice for a survey of surveillance and electronic privacy law. For instance the article fails to mention that, at the time it was published, Google required search warrants for all e-mail -- an important detail.
