Thanks to reveals like Echelon (https://en.wikipedia.org/wiki/ECHELON), every big/strategic (e.g. energy/arms) business in Europe has been aware of this since the late 80s (at least). For instance in the 90s, a common strategy when negotiating with US companies was to send misinformation via email or fax internally knowing that the NSA would pass it on. From the results of the negotiations it appeared that the NSA were not aware that they were being played in this way.

Anyway, so that's why I think you're not hearing too much about that scandal - it comes as no shock to anyone it affects.
