The export control angle is interesting. I was treating addiction, radicalization, capitulation to authoritarian govts, abetting human rights violations, productivity loss, etc., as the symptom of a common cause: the hyper-optimized engagement model and curbing it with a policy. You're right that some of these harms might warrant categorical exclusions rather than pricing the whole business model out.

I may have had an overly optimistic ideal of people running small federated mastodon servers for friends and family for free/donations being the only type of "social media".
