Your point well taken, but my issue is not so much that these companies decided to terminate his employment. I think that was cowardly and in essence caving to an imaginary mob, but let's leave that aside.

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.

I think the point in this case is pretty simple. A company can't employ this guy and also credibly claim to be concerned about creating a safe environment for women at conferences and other events. There's nothing 'exaggerated' about that.

Sometimes actions have long-lasting consequences. Apologies can't magically wash those away.

There is an assumption being used by these companies, and Twitter generally, that I disagree with: "Once someone has behaved in a certain way, they can never be trusted not to behave in that way again".

I think people are judging on a case by case basis. But in general, if you do something very bad, it is very difficult to persuade people that you've genuinely changed. How could it be otherwise?

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?
