Except this guy wasn't a journalist and he wasn't a whistle-blower and he wasn't a documentarian. He was an employee of a company providing a service who was exploiting the access (and presumably paid-resources) to pursue his own agenda. They don't owe him an explanation or benefit of the doubt or anything else and he doesn't raise any questions and there isn't anything of interest in his commentary that suggests it's deserving of any followup. This smells of someone wanting to play 'Morgan Spurlock'.

Google might be evil. They certainly aren't pure of heart and all that. But there's nothing in this ten minute monotone "expose" that really gives any legitimate concern.
