Putting the company to death isn't the same as putting the name of the company to death. You're thinking of the latter. Actually putting a company to death would mean aggressively seizing and liquidating all assets, spending those funds on public interests as well as banning all the executives from ever working for a similar company as long as they live. Then new laws would be created to assure the exact same fate for any other company to follow in their footsteps. Will it ever happen? Probably not. But that's how you kill a company.
