If really considerable time elapsed ...
... after the captain was made aware of the note and before the diversion, I do not understand the decision-making process.
Either the note is taken seriously, then land at the nearest suitable airport. Why wait for a fire alarm? Or wait for people on the ground, whose lives are not at stake, to make the decision? It might be too late then.
Or the note is not taken seriously, then just go on to your destination.
What is the logic here? "Oh, we have been flying for a while since we saw that note and there is no fire, now let's divert."
