Can we start talking about important things again?
That being said. If I was currently at Twitter in a high value position, I might also take the opportunity to get myself publicly fired. Maybe not in a fashion that is as rude as this particular example, but I'm guessing that even this display is still good exposure in terms of getting promptly rehired elsewhere.
We're in an in-demand field. Most of use exploit it by wearing programming joke t-shirts (again, not the rude ones) in dress code companies where we get away with it as long as we can dress up for when it matters, but I can certainly see why you'd want to get aboard the wave of people getting personally fired for correcting Elon Musk if you had no interest at remaining at Twitter under his leadership.

So you might as well do it publicly.
