I had a similar reaction. I respect how bold it is, but I still think it's pretty fanciful. I suppose I could see the part about social media being a public health issue, but I don't think it's super realistic that the government would straight up be shutting down sites, which to me reads like some kind of bad fanfiction. More likely it would be the usual churn of testimony before congress, news about antitrust cases, new laws requiring some kind of new disclosure, etc.
