I don't see a way for government regulation to restrict social media companies from gaining market dominance. Even splitting doesn't help. You can try to split the main social network off from some other profit-generating activities, but they would probably start those up again, after some time. You can't split the social network, because then users of the smaller parts just join the bigger part again. Currently we don't know how to do it, except encourage new companies to rise.
