For Twitter, his plan is the opposite of hyper growth. He doesn't just plan on bankrupting it, i.e. making Twitter's debts unmanageable for its revenue and assets. No, his plan is to actually ruin the company and any of its remaining brand identity. He has to destroy all potential value there, so nobody else can pick up the pieces and show how much of an idiot he's been.
Also, that has the added value for his investors that no one will be using a revived Twitter to instigate any revolutions in say...somewhere in the Middle East.
