Just to play the devil's advocate, one might just as easily argue that the self-selecting of you and your like-minded peers actually made the NSA's recruiting tasks easier. If you have some moral / ethical / rational belief systems that are inherently incompatible with their organizational DNA, a perfectly efficient recruiting machine would have sorted you into the "NO" pile anyway. Likewise, people more well-suited (for the sake of making ourselves feel better, we'll call them morally challenged) - might now be more inclined to sort themselves "in." So, they might have merely saved themselves some additional interview analysis and (assuming a less than perfect screening process) perhaps even prevented another Snowden Affair.
To be clear, I am not asserting that any of this is true, but I suspect that my unfounded speculation using incomplete data is no less reasonable than yours.
