I think it's more an issue that non-sensitive data can still be harvested and turned into sensitive data. So for example, troop movements are sensitive. They probably wouldn't be coordinating those over unofficial channels. And normally if, say, a soldier says "I love you" to his family, that's not really sensitive. If all of a sudden, 40% of the soldiers on a base do that though, that's leaking sensitive data.
