I used to work in those circles ~15 years ago and the short answer was: Yes.

It turns out that an absurd amount of sensitive/national security information is actually public but it becomes sensitive once it's organized in a way that it becomes "actionable" for attack, compromise, etc. In my particular situation, an acquaintance studying operations+logistics had overlaid communications trunks with transportation hubs and realized many of them were one in the same.

Now that more of this information is available easily and in readily combinable forms should make us re-evaluate all of it and how much gets shared, with who, when, and to what detail.

Btw, this is also a reason you should be skeptical whenever there's a leak and someone claims "none of this data is classified!" While technically true, a piece of non-classified but relatively unknown information might be the missing piece that makes something actionable.
