I get where you're probably coming from: this same technology is used all over the world to target journalists and dissidents in countries with and without the rule of law. A very real concern. I wouldn't do this kind of work either (also, it's been over a decade since I had the chops even to apprentice at it).
But there are very coherent reasons people are comfortable doing this work for NATO countries. Our reflexive distrust of law enforcement and intelligence work is a fringe belief: a lot of families are very proud to include people working in these fields.
The most important thing I guess I'd have to say here is: our opinion of this stuff doesn't matter. At current market rates every country in the world can afford CNE technology, and it's a market well served by vendors outside of NATO.
