The correct answer is No.
The First Amendment Rights are not guaranteed in every situation. The First Amendment protects citizens from the government punishing or censoring speech - Federal, State, and Local governments. But it doesn’t apply to private organizations, this means that private platforms can ban speech, or fire a worker based on speech.
There are unprotected categories of Speech, this means that there are several categories of speech that the First Amendment does not protect they are: true threats, blackmail, defamation, solicitation to commit crimes and others.
