If you are a director of a company facing such a situation, it's what you want to do. Because if you don't, you become personally liable for the missed payroll. Do you want to close up shop and say "this startup died because of SVB, on to start another one", but keep your car and your house, or do you want to risk losing literally everything you own and then end up with loads of new debt on top of that.
Depends if you think the eventual outcome is worth more. People used to second-mortgage their house to start small businesses where the best-case payoff is much less than these tech companies-- some of which are apparently the next Google or Facebook according to the head of YC on CNBC yesterday
