That's the thing. You don't know. Nobody knows except the CCP. That's the problem.
But you do about every other social media platform?
Fake news is not exclusive to a single platform. Teach your family about reputable news sources and stop trying to shoehorn US propaganda down everyone's throats like it makes you look smart. Tiktok learned everything it does by the likes of facebook, Google and Twitter.
Why do you think US social media is everywhere all over the world with near instant or sometimes even get higher bandwidth preference in some countries? If you don't think the US government has nothing to do with the level of complexities that entails dealing with local governments/infrastructure and planning, then I guess "ignorance is a bliss", and I hope the US government will bring you peace and much freedumb. Don't complain when they come in blasting tho.
