More like our government fully understands how to weaponize social media to spread their bullshit, and how valuable it is for mass control and surveillance. We're more than ok with our social media platforms because of this usefulness, but TikTok is China's version and we can't have that type of mass surveillance and control and propaganda in anyone's hands but ours.
A few years ago this would have sounded like a conspiracy theory. Now it's the only logical conclusion.
Our government (well, our congressmen and women) demonstrably has no clue what social media is capable of outside of their meta sponsored talking points.
Tbf, China doesn't allow US propaganda in their country either, i.e Facebook and co. They even banned or make it impossible for stuff like wikipedia and google to work over there.
