I was worried about this as well (to a point that when Google reached out to me, I told them thanks but no thanks, given all this). They eventually wore me down and the process was actually quite painless. I have been here for 3 years now, quite happily.
They tried to wear me down, to the point of contacting me multiple times a week, via every means of contact possible, for weeks on end, until I threatened to take them to court because they were harassing me after I asked them to stop contacting me.
Every single one of those contacts, by the way, was by a used-car-salesman type of "recruiter" who would blow smoke and not answer questions, etc.
There was no way I was going to ever work for google because of their lack of ethics... but this didn't matter to them. And their persistence despite being told that only confirmed the view.
Edit: Sorry my experience doesn't fit your desired view of Google. But if pointing out facts that don't fit someone's ideology gets me constantly downvoted here, what is the purpose of participating in this site? Is this only for circle jerks?
I was mightily tempted to downvote you, not for the substance of your comment but for the complaints about downvoting. Up until the complaining it was interesting.
