It doesn't have to be lifechanging to be meaningful. I'd happily take 6 months of severance over working ineffectually on a doomed product.

Imagine you're a middle tier functionary making $70k a year. Are you telling me $90k in cash after tax plus unemployment for ~6 months isn't lifechanging? That's a downpayment on a house, or your student loans paid off, or $4000 a year in permanent income for the rest of your life.

If yiu get severance, generally you don’t also get unemployment
