You are worrying about domestic nation state actors, and you are calling social media to be banned by whom? Some mysterious administrative entity that is surely not a part of the domestic nation state doing the very propaganda you are railing against?

Surely the people with the power to ban the lot of social media don't have their own propaganda to shove down your throat. Surely they will only ban the bad ones where foreign agents spread dangerous ideas and keep the good ones where only upright citizens of their own country can talk about how great everything is.
