"They are willing accomplices to this action and pretending otherwise is disingenuous. Evidently these engineers lack a moral compass and their word means nothing. If they had a problem with this action they could easily have spoken up and taken action but they took the easy path and did nothing.

Based on what I have seen from Google it appears this is part of their culture, the "Google way." Their constant interaction with and ease of access to high level political officeholders is incredibly concerning.
C.S. Lewis said it best:
One can only hope that Google is just a bunch of crooks willing to sell us all out for a dollar or two. However, if they view themselves as our overlords of change, ushering us into their vision of a gilded future for our own benefit, well, were all fucked.
