How would you apply this directive to the particular situation we
found ourselves in this time?

As a reminder:

* Around 3 December, we didn't think we'd be ready to release until 11 December
* The security team had already set an embargo for 12 December
* Our PR people advised us that 13 or 14 December would be the last
suitable day to announce a release in order to have an impact before
Christmas
