Why would someone leave a company immediately if it was under good terms? Or is it just the case that this wasn't public until today?

[raverbashing]

Because any more time the person remains there is giving information to a potential competitor (and there's no point staying if you don't want to be there anymore)

I think Marissa Meyer gave Google a half hour notice.

Marissa resigned by e-mail and just didn't come into work that day.

Especially in the case of high level manager leaving voluntary, I would expect him to leave with proper few weeks notice.

Giving company time to shift responsibilities to other people and all that. Spending day or two explaining things to whoever will take his place.

Leaving right now should be nuclear option if you have no other choice or was treated very badly.

He probably gave notice and this just was developed privately until his time had come. It's wise to do this kind of thing in the background. Subordinates are more likely to question the decisions of someone that they know won't be around much longer, etc.

Because typically when execs leave, they tell their boss first, arrange a transition plan as a team, and then make the announcement after a plan is in place, effectively immediately. What's unfortunate is that this isn't how much resignations work.

If his reason for leaving given here is real, then they probably knew for about a month:

Thanks for the link. As an aside, I've always found it baffling that G+ URLs are a cryptic as the above, particularly as they are 301'd to be more legible after the fact. e.g. The above link is redirected to https://plus.google.com/+VicGundotra/posts/MFrDF3W4RJL
