Maybe I just don't want a platform controlled by a country actively committing a genocide to be able to shape the narrative around another genocide? Maybe I don't want to offer a country that kidnaps and retrains dissidents access to data they can use to target foreign dissidents? Maybe I think that a power that actively targets American institutions with cyberattacks on a regular basis shouldn't also have access to the minds of millions of Americans via an algorithm that is seriously, dangerously addictive?

Like in what world are people seriously coming to the defense of China? What, we suddenly trust a dictatorship that openly and brazenly wants to destabilize Western nations? We trust that ByteDance is very independent and totally cool and doesn't have to support the CCP at gunpoint at all?

I think people are massively understating the power that control over these platforms offers, and massively overstating the impact they have. Massive protests were successfully organized way before TikTok, they will continue to be organized after it is gone. This isn't the herald of the end of social media in the U.S. If anything, perhaps a Fediverse alternative could spring up to fill the gap, which is by far the best platform for organizing.
