Because as a Google employee they understand what is and isn't done as a matter of privacy?
Do you have any evidence that Google spies on its own employees for the purpose of giving them privileged manual treatment when they don't ask for it?
Do you have any evidence that Google create associations between separate Google accounts to the extent of treating them as the same accountholder (asside from deleting duplicate spam accounts)?
Some years ago, I watched some historical TV show (could be Rome?) where one of the characters has been diagnosed with some disease, so I wondered if they knew how to properly diagnose it at the time the show was set at. So I used Google to search for the disease to get to its Wikipedia page. Then I almost forgot about it.
For months after that, Google bombarded me with the links to the disease and cures and remedies and whatnot.
I remember even seeing that at my kid's gaming PC, and I don't remember ever logging in to my Google account there. We only shared the same IP in the household.
That's pretty anecdotal, I know, but that's what there is.
If there was any such evidence, it would only be known to a small subset of people who work at Google. The only thing anyone else has to go on is very general privacy policies and Google employees commenting on forums! The public only has an absence of evidence, not evidence of absence.
