Does anybody care?
There's no doubt that Huawei is China's 'Motorola', and that it's an exciting and innovative company; but its strategic alliances with China's establishment would make it a very risky partner for any Western hi-tech company.
However, in the case of Symantec it probably doesn't matter. Any 'security' company that's been so successfully hacked and violated as Symantec means that it's probably worth stuff-all to the US government.
So why then would the US Government be interested anyway (unless it's some kind of honeypot trap)?
