I don’t think there is a Republican foreign policy or something that’s coherent in any real way. Biden’s withdrawal comes directly from Trump’s deal so this is a major legacy not just of Biden but of Trump, so I think that complicates the whole story.
Looking ahead, the Taliban will certainly want to use technology for its own PR and propaganda purposes. But now that it has taken over Afghanistan, it will in all probability want to restrict social media access to the Afghan population in its bid to reduce their access to information. Platforms like Twitter and WhatsApp will have to figure out how to deal with the Taliban's propaganda, while still trying to ensure that Afghans retain their access to these platforms if the Taliban attempts to restrict access.
