I didn't downvote you, I appreciated your commentand it underscores my larger point. Freedom of speech isn't freedom from consequences, and there very well could be public backlash for this, or any other comment. Private organizations can enforce consequences on employees or stakeholders for falling outside their prescribed internal policies. Also, saying generally offensive things can certainly alienate somebody in society or professionally. I don't think this particular case the joke went too far and was certainly written by the oscar comedy writers and probably not by Harris himself.

To your other point, on a private platform people certainly have the right to deem what is acceptable communication. I agree with that, certainly. In really no case is a form of speech 'beyond criticism'.
