Both sides say it's worth banning "Tiktok/Google for granting the CCP/USA the ability to algorithmically influence the views of Chinese/Americans".
We never discussed this seriously before because we held a monopoly on it. For decades, other countries provided us with a direct feed of their data. Only recently have they begun to grasp the ramifications of that.
China never bought into that narrative. They have consistently upheld their data sovereignty policy, requiring foreign entities to host servers within their borders to operate, and that looks like the direction the rest of the world is heading.
I wish for an open world where data & communication flows freely, but it's unclear who can be trusted to wield that power.
Meanwhile China's reasoning for blocking US companies has been eerily similar arguments the entire time. Hard to prove them wrong when we have the major aristocrats of US tech companies completely prostrating themselves at Mar-a-Lago, offering bribes (er, sorry, the going term is "funding inauguration parties") to the incoming administration in broad daylight, staffing themselves with party officials, etc.
Arguably both are right, and it's a shame because the general working class people of both nations have more in common with each other than they do with their ruling classes. I think the thing that terrifies those in authority the most is the idea that the citizenry might realize this if there's enough communication.
