While FB's perceived threat was(is?) targeting of users on behavioral models, for misinformation campaigns. Tiktok's goes beyond this, with a state actor pushing its propaganda with active blessing of the platform itself and curbing dissent against itself. Considering how we have seen companies self censor for CCP, I wouldn't say the curbing dissent thing is far fetched.
On a similar note, I used to consider SCMP reporting of high standard different from Xinhua/CGTN and free from interference as it was based in HK. But lately I have seen them publish stories to push CCP agenda without proper fact checking.
