My read is that Bostrom had reason to believe that the email would come out either way, and then he elected to get out in front of the probable blowback.
That said, it’s not entirely clear whether Bostrom knew the email specifically was going to be written about or knew that someone was poking around in the extropian mailing list and then guessed that the email would come out as a result.
In any case, I think it’s unlikely that he posted his apology for the email unprovoked.
