I'm all for supporting law enforcement efforts, but the wording seemed to imply that Apple hands over any requested info to the FBI, which seems excessive.
But I was mainly pointing out that quote because it wasn't clear what lesson the parent commenter wanted Google, Facebook, and Amazon to be learning from Apple. I would have guessed it'd have something to do with protection of user data, but the letter says they turn over any user data they have!
They probably refer that they have handed all the information they could in this specific case. There surely was some kind of authorization (from a judge perhaps -- US law is almost unknown to me) too.
As for the comment of Google, Facebook, etc, learning, I agree with you.
