Here's the thing:

Every country that CAN collect data IS collecting data.

If they are manufacturing anything that can be hacked to collect data and they can feasibly get away with it (read: there is no independent oversight), you can bet it is being done.

Germany is no different than France is no different from the US is no different than China etc. etc.

The only difference is they haven't had their Snowdens come out of the woodwork yet.

I can guarantee the US intelligence apparatus is right now trying to figure out how to out a few of these foreign programs so that the US does not look quite so bad in comparison without causing a diplomatic meltdown.
