This is exactly how business works. You should not be surprised. Their job is to ensure the company survives and that is really it. Everyone is expendable. None of these employees were guaranteed a long leisurely employment at Stripe.
Businesses change overnight. But it's always a cyclical market. As the founders I would expect them to benefit themselves. There doesn't have to be consequences, only change and adaptation. It's just business, they aren't your family.
This is all complete nonsense. They're handing out millions of dollars they have no obligation to pay. Unlike cheap talk on the internet, this actually costs them quite a lot. This is extremely generous.
I would still take the deal. I would work there if they hired me. If there are enough people like me to continue the business, then this thing turns out to not be shitty. Only time will tell.
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.
