It speaks well of Google's openness that Brin's response is a quip about how long it was, not a serious comment about how such discussions should stay internal.

If Google were to fire Yegge, it would be for (voluntarily) deleting the post, not for accidentally making it public. When he publicly posted it, everybody was talking about what a great work environment Google must have for people to be able to talk so openly. After he deleted it, lots of people inferred censorship and Google's reputation suffered.
