I don't think being a shareholder gives you such rights. Even so, the guy in question probably had more shares than you thus trumps your desire to be a busy body.

Lets see you walk on the google campus and demand to see who has been reprimanded recently to some random manager. As you are dragged off the campus yelling "but but but I am a shareholder....."

But beyond that it is more likely he had a exit plan under which he was guaranteed such money when he joined google, bringing his baby Android. And as I recall it it was not as cut and dry of a situation as everybody likes to make it out to be. It never is.

So you can be outraged all you want, and perpetuate phantom "rights" of being a share holder, but at the end of the day you are not helping the situation.
