A few hours after Microsoftover Google's new privacy policies, the Web giant responded with a blog post noting that Microsoft has a similar policy regarding sharing customer data.
Betsy Masiello, a Google policy manager, took to the company's public policy blog to rebut "myths" that she says are being falsely spread in the wake of the Google's that allow the company to share user information across different services. And she specifically singled out Microsoft for stoking those fears, noting that its privacy policies state that "information collected through one Microsoft service may be combined with information obtained through other Microsoft services."
Masiello also pointed out that Google offers users tools to manage their privacy settings and retrieve data from its various services if they leave them, something, she says, Microsoft's products don't match.
"We've always believed the facts should inform our marketing--and that it's best to focus on our users rather than negative attacks on other companies," Masiello wrote.
In an e-mail exchange with ZDnet's Mary Jo Foley, Microsoft's top spokesman Frank X. Shaw noted that "there is a difference between policy and practice." Microsoft, he went on to say, doesn't read customers' e-mail, for example, though Google's reading of that mail is done by a computer, not a person, in order to target ads.
