Vint took what could have been a prestige emeritus position at Google and turned it into a platform to champion accessibility and “Greyglers”. The man has more class than his suits.
I personally witnessed Vint give valuable advice to managers like me, often in difficult cases. It sounds banal but often in a large corp you know what you need to do, but will have a lot of - justified or not - doubt about whether you can get through the bureaucratic molasses and the political interests of your higher ups. Vint's backing enabled a lot of people to do what's right.
One of my colleagues has printed and framed a reply from such a thread, where he offered an opinion in support of another manger. Vint replied "This is good advice. V.".
