Cultural Offering analyzes the video of the Google executives shortly after the election.
I suspect that most, if not all, of the executive teams I've encountered over the years have had a diverse range of political opinions. The opinions are usually hidden but whenever some have surfaced it was quite clear that the places aren't echo chambers. I've always regarded that as a plus.
The assumption expressed by the Google execs that most of the people in the room shared the same political views would certainly send the signal that if you don't have those views, you'd better keep quiet.
