This seems not to be an opinion that other people hold, but I never saw social media as “free speech” given that some third party can decides which parts of what you say get promoted.

If you sent letters to people via a middleman who decided which of those to forward onwards, you’d see that as censorship. I appreciate that that’s an over-simplified example - it’s meant to be a reductio ad absurdum. But control of the algorithm effectively regulates free speech, IMO.

Also (for clarity) the fact that China happens to be involved is not relevant to my point!
