This argument could be applied to any technical progress.
Email for example: "Sure you could dePend on a soulless money making machine to optimize your communications... And hope it does it right. Or you can just take control of the situation and do it the old fashioned way: letters and stamps."
You have control over email: providers, client applications, encryption. Sure, many many people use gmail and gmail isn't too different to facebook in this regard, but email itself is an open protocol where you can use a competing service and still integrate with others.
Or you can just take control of your relationships and nourish them the old fashioned way: calling, email, face to face, etc.
