Given that Apple spent a lot of money last year resisting USG efforts to decrypt their smartphones, it would seem they're an especially trustworthy steward.
Except the part where they immediately agreed to help the US Government, only to find that incompetence had made the problem much harder than it should have been. They then resisted having to do a large amount of unpaid labor to continue to help. Plus, a PRISM member.
To avoid confusion for any readers, you should clarify what this means: Apple has an automated process for serving data in response to any approved FISA court orders from the FBI.
It's not even clear that PRISM implies an automated process. It appears to just be the NSA's internal name for the process of using the FBI to request stored data from service providers.
And to make this clear: U.S. companies must comply with valid court orders. Being a "PRISM member" is not optional.
