Jack actually walked out of the Twitter meeting where they were explaining the layoffs to the leftover employees. I'm sure he had an important meeting though.
I really think the future is bleak for both Twitter and Square.

In the most charitable light, I believe Jack doesn't want to be seen as a villain. In a less charitable light.... I think most people can read between the lines.
Those can't or do not wish to see any ominous signs here, tend to be still working at the company. Willful ignorance of this kind is completely understandable, in my mind, since few wish to bite the hand that feeds them.
Having put superhero efforts into a few roles, I can relate to that kind of behavior.
