The German's knew about this a long time ago. So did the other "allies". Now that it is brought into the public eye, they are aghast.
What they are really complaining about is the continued existence of the "five eyes" intelligence network. This loose organization dates from the 1940's and is the most exclusive alliance in the world. Membership is limited and closed. Members have the luxury of access to world class sigint. Germany, Japan, France and the others are jealous. They know they will always be targets and will never be full members.
