Always read any proposed law with the worst possible intent, implementation and application you can imagine.
Yup, that right there.
I truly believe that tiktok is part of Chinese fifth generation warfare against us. In China, all the tiktok challenges for kids are things like, "Be the first to solve the calculus equation", or "post the most impressive science experiment".* In the US it's, "Who can eat the most tide pods."
I'm just not sure bans and censorship are the answer.
*Admittedly, one of the reason the Chinese tiktok challenges are all intellectual is because the CCP monitors things to make it so. Without that threat, they might be doing tide pode challenges there too.
