Is X vulnerable to Chinese government interference because its American executive has other business interests in China at stake?
I’d argue the TikTok remedy should be applied to X, too.
No, X doesn't have a corporate governance structure that requires Chinese government control, because it is a US company.
Companies in China (and especially those of prominence) have formal structures and regulations that require them to cooperate with the government, and sometimes require the companies to allow the government to intervene in operations if necessary.
It is not possible for a CCP official to show up to a board meeting at X and direct the company to take some action, because that isn't how US corporations work.
This should be applied to all social media.
