I love how people who don't use Apple technology make claims such as "Facetime Audio voice quality is dreadful," when it is the same voice quality used in video made with iPhones, which have been used to make first run commercial movies and television shows, television news work with perfect clarity, enterprise grade tele-conferencing, and training videos. . . as well as thousands of podcasts. Ergo, what you just wrote is just FUD. I use FaceTime regularly and the quality is superb.
Angela Merkel's just discontinued using an iPhone because of the Obama administration's NSA monitoring of carrier traffic and the erroneous claim from Snowden that all Apple iPhones were compromised by the NSA, which has been shown to not be possible, and was actually referring to Android phones, iPhones that had been physically intercepted to install specific hardware/software, and RIMM Blackberry phones that were also intercepted. Merkel's anger at the U.S. resulted in the German government going back to RIMM Blackberries.
The German decision was motivated by a mobile security solution from a German company, Secusmart, which was subsequently acquired by Blackberry. Secusmart developed the product for Blackberry OS 10, but not for iOS or Android, because they are not secure. About 4,800 German civil servants now use BB OS 10 cellphones with Secusmart chips, not just Frau Merkel. The decision was well researched.
If the facts were as you state them, a decision made in anger based on erroneous information from Snowden about a secure Apple product, then Apple would have convinced the German government to restore the Apple relationship and Secusmart would have developed a solution for iOS phones. You paint the German government as gullible and Apple as inept marketers: Occam's razor
