Google has internet searches. As well as often locations and journeys (Maps; Android). What a user watches (YouTube). Their emails (Gmail). What they do online (Analytics).
Facebook knows personal details, mood, etc for people who explicitly choose to share these things with their friends, or participate on Facebook in other ways. This may be an oversimplification, but I suspect Google is able to learn much more about a user passively than Facebook is.
Of course it'll differ for different people, but on balance I'd say Google knows _a lot more_ about me than Facebook does.
(...And they probably both know more about me than I do.)
So yes, this news may affect Google, but I disagree that Facebook has an advantage over Google when it comes to knowledge of users.
