There's the threat of significant regulation. I think there's a reason why Zuckerberg feel the need to go in front of Congress, rather than telling them to go bark up a tree. It's also quite amazing how quickly all the payment processors shut off WikiLeaks, based on pressure from US senators.

Companies can, however, be banned from the US for overtly political reasons. See Huawei and ZTE.

I agree that Chinese CEOs walk on thinner ice personally, and that they can be thrown in prison or worse much more easily. That's a general problem in China. However, the easy way in which Americans claim Chinese companies are run by the government is not true. It's also true that large US companies are thoroughly embedded in the government and vice versa (the massive defense sector, parts of the tech sector).
