Wouldn't want to work with this guy. Fair points but come on, the poor recruiter is the wrong person to rant to.
Why? If enough talented individuals reject a Google position (or more accurately, entry to Google's interview process) for moral reasons, the message will be sent up the chain of command.
Google thrives on talent. If it becomes hard to acquire new talent, they have a serious problem.
With only a little bit of sarcasm, I would also say that accepting the job offer, working loyally for some amount of time, and then quitting in protest would be a much stronger signal still.
