The blog post also says this:
"(...) I understand that every OS has diagnostic functions, however these services break the promise that Apple makes with the consumer when they enter a backup password; that the data on their device will only come off the phone encrypted. The consumer is also not aware of these mechanisms, nor are they prompted in any way by the device. There is simply no way to justify the massive leak of data as a result of these services, and without any explicit consent by the user.
I don’t buy for a minute that these services are intended solely for diagnostics. The data they leak is of an extreme personal nature. There is no notification to the user. A real diagnostic tool would have been engineered to respect the user, prompt them like applications do for access to data, and respect backup encryption. Tell me, what is the point in promising the user encryption if there is a back door to bypass it?"
