But in the face of fundraising headwinds, a decision to cut costs like this only improves (or stabilizes anyway) their ability to raise at a valuation closer to what they're looking for in this down market. The severance package here only deferred the benefit to the bottom line, but it wasn't a consequence for over-hiring and potentially disrupting lives.
In other words, the layoffs actually benefit the founders directly, and it ends up becoming a perverse incentive to over-hire and lay off again with the next boom/bust. Successful accountability means people actually avoid doing shitty things.
