Twenty five years ago, when Steve W. worked for a military subcontractor, he'd often roll his eyes when meetings were denoted "CONFIDENTIAL". It's not that he didn't take confidentiality seriously, it's just that everything they did was confidential. By labeling most everything "CONFIDENTIAL", there was no way of knowing when some things – like performance reviews and should-we-fire-so-and-so discussions – were really, really confidential. At least, not until you were actually in the meeting.
