There's a difference, facebook did not attempt to run its social media business in China, and Google voluntarily quit so it doesn't have to comply to censorship law. Meanwhile Tiktok has a US branch and is complying with laws in the US.
China has a restrictive internet where if you want to operate, you have to comply with a certain set of rules that are unsavory to say the least. Facebook, Google decided to not bother instead of complying to those rules, but they very well could have, Bing and Amazon is in China.
Tiktok's US branch did not violate any US law and its being prosecuted with administrative action, which is why your equivalence is false - The actual equivalence would be to make laws that enforces ownership for social media companies and make them store their content in location. And enforce those laws, like China did.
