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".

I appreciate your optimism actually. Someone (it's me) can also share your ideal for social media while also having slightly different takes on what makes the prevailing model wrong exactly.

Thanks for the back and forth.
