I believe your reading is incorrect (and the reading of other commenters here is more correct).

Bandwidth.com will tell MyLocalPoliceDepartment that Google Voice is the "wholesaler" that controls my GVoice number. Bandwidth.com has never heard of me (nor I of them, until today). They don't have my information to give. They can't "confirm that I own a particular number."

They will, however, tell MyLocalPoliceDepartment that they should be barking up Google's tree without a subpoena, which I don't mind so much. I have entered into a relationship with Google. I would expect them to respond to well-targeted and legal subpoenas ordered by a judge.
