I smell a rat here: Huawei Australia increased its year-on-year 2012 revenue levels by 61 per cent to $368 million AND THEN.... Aussie Spy Agency plans "stolen" by Chinese... LOL
On a serious note, most major networking companies have been accused of having some sort of "backdoor(s)" in the past... What/When/Who to believe - that is up to the reader.
As for Huawei: Their USB 3G dongles are temperamental at the best of times (personal experience). Their networking kit is apparently pretty good and robust (non-personal experience...).
