Keep in mind the framers of the constitution in the US realized this type of issue, which led to the Bill of Rights protecting things like free speech and other government encroachments on individual liberty.
I appreciate that corporate platforms are different than public spaces when it comes to free speech, but we've got a long way to go before US society broadly tolerates censorship by foreign entities (at least, I hope).
US Bill of Rights was originally written more to protect the states against the federal government. It couldn't even be enforced against the states until the 14th Amendment provided some vehicles for incorporation, and the courts acknowledged them. And even then the process of incorporation is still ongoing - e.g. the 7th is still not incorporated.
