Because we exactly didn't. Look what's flying over your head.
China: censors free speech in China then makes a US speech platform and censors American speech on the new platform. Blocks US platforms in China because they refuse to censor speech for the CCP.
US: blocks China from owning speech platforms because the US doesn't allow censorship and doesn't trust China to stop censoring speech on the platform.

Are you a habitual TikTok user? Or do you work for the CCP?
I'm openly suspicious that you might be getting paid to conflate these very obviously opposite things.
