I guess I don’t understand it, because I am using this free service, every day and multiple times a day, just like I do for Google.

How can we not understand that in order for Facebook to survive and continue to offer us this service (obviously we all love and use Facebook, some for business, but mostly for friends) they need to linked pages. Just by doing that one thing they will rise in many Google SERPs.

Do I trust Facebook, no. But will I still use FB, yes.
