Severance is basically marketing for future hires. You hope, as a company, you will be around in a few years and will be hiring again. If all the employees laid off during tough times get severance, then the company can say "even if we hit tough times, we have a track record of doing the right thing", which is attractive to future employees they are attempting to attract. Since the company is dead, their reputation doesn't matter.
