Google's DLF - The data privacy connection

I rail on Google, but they're a long way from Facebook on Gordon's scale of corporate evil.

Facebook has zero-forwarding email. Google has the Data Liberation Front -- and they take requests. There's no comparison.

DLF fan that I am, though, I was puzzled by an alleged connection to customer privacy ...

google's letter to privacy commissioners. DLF cited as "[an effort] to protect customers' privacy and promote transparency."

What does data freedom have to do with customer privacy? Sounds like PR-speak. I could think of only one connection, and the DLF confirmed it for me:

Data Liberation gives people a way to revoke their trust in a company if they're not pleased with the way the company is behaving.
