That's old and "expired" data from over thirty years ago and the family member I'm discussing is open about it, now. What needs to stay quiet (in this instance) is operational details, not that this person did the work. So your point doesn't really stand. I felt it was useful information and it was information that was safe for me to share, so I did.

The Financial Times article is, of course, intended to promote the service to women and it really doesn't hide that fact. You can bet that MI6 reviewed the article before it went to publication and everything in there was vetted a thousand times. It wouldn't shock me if small, fake biographical details were added into the article to obscure who these people really are. We don't know. The fact is, though, that since this piece is probably meant to advertise the service and-- given where it was printed-- it's probably directed at Oxbridge women. That is, women who have more job mobility than most. MI6 wants women to know that they won't be viewed as honey pots and that they can have a family. So the article is probably going to be an accurate representation at some level: since these particular women can leave if they want to, you don't want to misrepresent what they're getting into if you intend to keep them.
