I don’t think this will have any real world impact. There has been an all out media assault on Facebook for some time now with no real usage impact. Mossberg‘s audience in particular seems like the least likely group of people to quit FB. Grandparents are going to stay on FB as long as they can keep seeing pictures of their grandchildren, etc... I don’t think anyone uses Facebook because it is “cool” (and thus susceptible to media tarnishing). They use it because their social network is on it and they value that.
