My life is quite a bit better because of both Google and Facebook, and I would say a significant portion of the amount of time I spend online touches one of those two entities. I really don't care that much about the privacy compromises for the level I use either. My experience is at least somewhat similar for at least a half billion to billion other people, so I'd say their impact on humanity is "pretty large".
