I think you are going to see at least the large nations throw up firewalls and crack down on the international social media companies because they have an awful lot of power to shape perceptions by silencing some voices or labelling their views as "misinformation" while promoting other voices. That's enormous power. It is absolutely naive to think that companies like twitter don't use that power to advance the political/social agendas their most powerful employees care about and it's even more naive to think that governments will see this power and not want to control it for themselves, but instead let it operate unchecked in their own borders, influencing their own elections. They will either block these companies from operating via firewalls or demand that they use their power to share the political and cultural values they want to push, systematically deplatforming any company that they view as a threat to their agenda. China was ahead of the curve.
