Do you seriously believe that? They are doing this non stop. Not a month goes by without my iPad requesting my iCloud password so it can back up my entire tablet, even though I've repeatedly declined to provide it.
They are collecting and analysing PII data all the time. They need it because it's an arms' race. They will only stop if compelled to do so by governments or by a privacy scandal.

Unless you tell me you never, ever use a search engine (not just Google, could be Bing or Yahoo or whatever), I am pretty sure you are in denial about that compromise. You are giving away private information all the time, you just don't realize it, or you are okay with the fact that "Getting good search results for this query is worth Google logging my IP".
