If I have a public platform and refuse to sponsor/publish/platform your speech, that is my free speech right! You don't have the right to force me to speak your words. Only the government is prohibited (by 1st amendment) from censoring/limiting speech (that does not cause or promote violence or injury to others). There are also some restrictions and protections also offered to the press (eg libel and defamation) and common carriers, along with the abomination of the DMCA.

Personally, I don't consider paid speech to be free speech, and I don't consider corporations to by humans, but the supreme court does.

Remember, facts aren't real, there is no truth, and crime is legal (in the current "Justice" Dept).
