We are all vulnerable to manipulation and should only read content that is approved by the US Govt.

Blocking another country's possible influence is not the same as ONLY being fed whatever the Government approves.

TIktok, due to the nature of the company's ownership and board directors WILL have Chinese Government influence. And they've already proven that they're willing to influence the internet to the point of controlling it 99% for their own citizens. China is the latter of the above statement. The USA and most other countries are barely even doing the former.
