Hang on a second there. We really have to go back to the history of Nortel, because the claim that Chinese hacking brought down Nortel really does not hold up.
Nortel expanded massively during the dot-com bubble, and went on a nearly $20 billion acquisition spree that caused it to lose money every quarter for years, even while its stock price was driven up by unrealistic expectations. Then the dot-com bubble burst, at which point these expectations were tempered and people began worrying about Nortel's unprofitability. The stock crashed, raising capital became difficult, demand for Nortel's products (and all telecommunications hardware) plummeted, and the company had to lay off 20% of its workers. At this time, Huawei was a tiny player outside of China. Nortel's major competitor was Cisco.
In 2003, for the first time in years, Nortel finally posted a quarterly profit, but then came under investigation from the SEC over suspicions that it was fudging its numbers (specifically, the accusation was that executives shifted revenue in time in order to meet targets that earned them bonuses). The SEC charged top Nortel executives with fraud, and the case was eventually settled, but Nortel had to change out its top management. Nortel was also sued by shareholders, to whom it had to pay billions of dollars in a settlement. There were layoffs and downsizing throughout this entire period.
To look at that history, and then to claim that hacking that might have helped one of Nortel's several competitors (and not even the largest, by a long shot) is the reason for Nortel's demise just seems completely out of left field to me. To be honest, it sounds like a batter yelling at the ump about being distracted by a fan after he strikes out 0-3.
