None of your objections so far have come close to resembling good faith rebuttals.

We have eyes, we’ve read the tweet, we (I would hope) know what invoking rm -rf / does. Presumably the context alone there and reading the room here should be enough to clue one in why one would find it specifically cringeworthy (even if I would probably use a tamer way to describe it-personally), and why perhaps one would in the exact same vein just find things funny for different reasons, or just find different things funny altogether.

Of course, I got the joke straight away and merely chuckled. Not necessarily my brand of humor, but hey, you buy the premise, you’ve bought the bit.
