This is where you clearly see Apple is all about privacy posturing and not much about actual privacy.

If they really cared about their customers' privacy, they would require notification servers registered with APN to push notifications encrypted with a key that only the recipient apps have the private key to. This would be true end-to-end encryption, and Apple would only relay encrypted notifications across, enabling them to deny all subpoenas and any kind of snooping requests from law enforcement on the simple basis that they plain can't even decode the notifications in the first place.

The very fact that they do have access to the notifications in clear-text is undeniable evidence that they actively want and do collaborate with law enforcement.

Meaning Apple's stance on privacy is utter BS - something anybody with a modicum of critical thinking suspected from the start, but now the evidence is crystal-clear.
