I noted several posts on the boingboing comment section that indicate Amazon is passing the buck to Audible, stating

while Audible.com is a wholly-owned subsidiary of Amazon.com, it operates as an independent site as well as a separate customer service department and all inquiries regarding Audible.com services should be directed to Audible.com.

Which is totally contradictory to the statement in the Washington Post

Audible’s audio books are wrapped in a layer of DRM, which Amazon does not plan to remove unless customers start to complain, Herdener said.

Amazon needs to step out from the PR machine and speak up for it’s customers! Keep at it and the door knocking should bring someone eventually!
