FWIW the ??!??! double trigraph as error processing is funny because of the meaning of ?! and various combinations of ? and !. It is funny and it has trigraphs. That’s the whole point.
But I am free to be curious and ask the author why he choose it! We are not computers but human beings! There is no HN rule that says that I cannot be curious and asks a question that arised from a thread but it is not connected to that! [1].

They chose it because the discussion is about trigraphs. It is not a particularly surprising choice to talk about trigraphs in that context.

I did not write that you did not follow HN rules, just that your question was very strange in the context. I did not downvote you, but I understand why some people did. Your question was a bit passive agressive, even if you did not mean it.
I gave the question a +1 because I, as previously stated, read it to be genuine curiosity. Maybe a smiley would’ve helped, I don’t know. ¯\_(ツ)_/¯
