Like it or not, Google is consistently ranked near the top or #1 on all of those "Best places to work" lists that get published from time to time. Everyone I know who has managed to get hired there sings its praises, and none of them have left (yet). I think it's unlikely that each one of their opinions is fueled by Kool-aid. There's something to it.
I don't think this guy is sad at all. I really admire what he did. It's pretty inspiring/motivating actually.
