Well, it does in that free speech is exactly the liberty of owners of non-government resources to choose how to control their use in expressing, relaying, and amplifying speech.
But “free speech” doesn’t provide any entitlement for any other party against the interests of the owners of non-government resources.
Where did the parent comment mention the government? They referenced the concept of free speech. That is not the same thing as the first amendment which is what you are referring to.
