To me it looks like that while the high-minded idealists remained mostly the same, it's Google that transformed itself into something completely different from what it was the early days. It should be noted that in 2005, when this guy joined Google, both Android and the acquisition of Doubleclick were at least 2 years away. Google execs were probably already planning the move into an advertising and spyware behenoth back then, but I'm pretty sure the lower "cogs" like any freshly hired techie, wouldn't know that for quite some time.
