1. A dev creates an app
2. 1+ million buys/downloads the app (did you see the missing 11 mln?)
3. The app is collecting all this information
4. The dev stores it
5. Anonymous uses SQLi to steal this info
6. Publishes it attributing to FBI agent who hunts Anoymous
First, not many apps have 12 million copies installed, not even if the app is free. So it is a very well known app like Kindle or Skype.
Second, big app producers don't get raided so much, because they are corporations with lawyers telling them to avoid risks.
Third, corporations don't need to get raided to provide user info. Their lawyers tell them to share it, or Bilderberg tells them to, and they are eager to betray their customers' info because customers are small fries.
Fourth, the FBI wouldn't have such info on hand unless there were an ongoing investigation, e.g. a political policing action, where literally millions of people are suspects.
Therefore this is probably an official betrayal by a big company like Amazon, telling the FBI everyone who has bought a book that condemns politically-connected criminals like Wall St bankers.

It's obvious that all of our personal data, credit card #'s, social security numbers are available to those people who are experts at gathering this kind of data. I don't believe there are really ways to FULLY protect yourself from others getting this info if they want it.
It can be done if you don't mind using Linux. If you want an iOS device however there is one way: Don't use an app unless you wrote it yourself
