Yes we should totally take google at their word when they say it's not politically motivated.
They can say whatever reasoning they want, that does not necessarily make it true. Google has a well defined history of lying publicly or hiding the things they do. Dragonfly, PRISM... These things take brave whistle blowers that have their lives ruined to reveal.
If I said, "I am going to eat this fried twinkie because it is for my health" would you take that as a factual statement (that twinkies are healthy) just because some PR department repeated it on my behalf? Google saying they are not doing this on behalf of the current administration means nothing. Nobody reasonable expect them to really be honest with the public/users anymore.
