Not irrelevant. The OP said that "no one is entitled to online speech". That's an unqualified statement which my link disproves. If they had instead qualified it as, "no one has a right to speech on Facebook", that's a different claim (arguably also false depending on the circumstances).
Once again, the statement was unqualified, "no one has the right to..." And once again, my link literally proves this statement to be false, because as you just admitted, at least some people do have that right.
But you seem to think "freedom of expression" == "freedom to say what you like", and that's clearly wrong because Europe has rights to freedom of expression (article 10) but you can't say what you like in Europe.
I'd suggest that you take the time to understand the links you post.
