The obligatory disclaimer: I am not a lawyer but…
The official Stack Exchange announcement, entitled An Update to our Community and an Apology, was deleted 18 hours ago. Possibly SE lawyers advised Ms. SarahSara Chipps to take this action. Possibly, Monica's lawyers demanded its deletion. Who knows. And no one will know because for legal reasons the agreement cannot be discussed in public.
I wonder if it is expected that Ms. Monica Cellio must delete any of her contributions as a sign of good will or as part of the agreement?
Perhaps not: Her question, Stack Overflow is doing me ongoing harm; it's time to fix it! is still visible.
