The vast majority of investigations are 'secret' in that they don't give out any details in the middle of an investigation.
Just think about it for a second. If you have done something really bad and you know they are looking into you why not leave the country or destroy evidence etc? Granted, there are a lot of downsides to both of those but people are probably not thinking rationally in such situations.
That "if" is doing way, way too much work in your sentence. Yes, I must admit it's possible CIQ's executives and engineers are hardened criminals waiting to flee the country the the first hint of an investigation.
But I find it very unlikely (the fact that they haven't fled being a rather important piece of information, no?). I'm far more willing to believe that the FBI (quite correctly) sees CIQ's data as a useful surveillance tool and is using it in active investigations.
That three of you guys now are going out of your way to (seriously?) argue the opposite seems just mind boggling to me. I mean come on: of course the FBI wants CIQ data.
