I call bs on this one, time will tell. Lennard Zwart is a guy who clearly has an economic interest in playing the 'don't host in the US' card. He wrote another article in 2012 about this with the same angle (see below, hit google translate if you can't read Dutch) and is totally vague about the call, does not explain why a C level exec would receive a call like that and did not report on making the required effort to verify the caller was indeed from the NSA.
I've received a number of calls over the years from people claiming to be law enforcement, and a whole bunch of email to boot, only a very small fraction of those were actual law enforcement on sanctioned missions, the rest were just impersonators and to do a first round of verification is par for the course in cases like this. "She said so" is not nearly good enough.
I'm a customer there, and from interactions I had with them they take data security and privacy very seriously.
Of course there is an economic interest in showing the disadvantages of hosting European data in the US. But what's wrong with that? That is simply true. For example: in some cases you break Dutch privacy laws when hosting data about individuals in the US (without taking special precautions).
