On top of everything else, this whole discourse is frustratingly Americanised. That XKCD cartoon is just laying out the inplications of the (outdated, written in a time when only governments had the power to censor) First Amendment.
I think you're reading too much into the original comic. It doesn't comment on whether the "showing you the door" is good or bad, it's just saying that when the following example takes place:-
a) Mr X is invited as a guest on a radio show,
b) Mr X says something which the majority of the listeners of the radio show think is terrible,
c) Mr X is uninvited from the radio show,
d) Mr X asks about his RIGHT TO FREE SPEECH
that Mr X's speech isn't protected under the first amendment.
It certainly doesn't say that you should be fired from your job for a tweet or a misunderstanding.
