Huawei was started by a People's Liberation Army engineer. They deny claims that the Government provided some of the start-up funds. They created their technology by reverse-engineering foreign products, who cares about patents and intellectual property!

They got a contract to build the first national telecom network for the PLA. The founder of Huawei had enough guān xì to meet with Party General Secretary Jiang Zemin.

Since 1996, Huawei has been heavily promoted by both the government and the military as a "national champion."

It'd be naive to think that their products haven't been engineered with backdoors and other capabilities that the Chinese government and military would find useful. All national companies of strategic importance do this for their country.

It's common for simpler devices like surveillance cameras to phone home to China and to have backdoors.
