Never heard of them.

When you lose 80% of your staff, you failed as a CEO. And when you do it like this... you deserve to be absolutely disrespected by your staff (old and new).

What would have happened had they not fired them? Maybe some loss of profitability (and importantly, maybe, or probably not), but probably not to the point where 80% of the staff would have had to be fired. Also it has evolved a lot between 2023 and now, and employees who were skeptical back then may have started adopted LLMs where it made sense.
