To which the HR person at the orientation had said, "Don't worry Google wouldn't do that." And this individual said, "I'm sure they wouldn't, that's why it seems like a no-brainer to put it into the agreement, it just says they won't do something that you and I both agree they would never do. I can't sign the document as written without this." The HR person took the updated version off to someone (presumably legal). And then after lunch this person was not in the group (I had seen them eating lunch) So when we had finished up, before my mentor had arrived I went out and found them waiting on the circle for a ride and asked them what happened. They said, "Google said no and also said they were rescinding the offer of employment."
And that told me everything I needed to know about how Google really thought about things vs what they said they thought about things.
