My contention is that this whole spiraled up from discovery of some bad behavior from the past, that seems to have been inflated into an exaggerated character assassination.
My contention with the grandparent comment is that "just don't be x" is not really an option if we are seeking redemption for past sins.
Sometimes actions have long-lasting consequences. Apologies can't magically wash those away.
Try thinking about it with Noah replaced by one of HN’s favorite ‘bad guys’. Facebook periodically puts out statements saying “Oops, sorry, but don’t worry – we totally respect privacy now”. How long would it take for you to believe that Facebook had really changed? How would you feel about a privacy conference accepting sponsorship from Facebook, and justifying this decision by pointing to one of the apologetic statements?
