I'm using one; given GCHQ/NSA/whoever already are watching my data, that UK ISPs use Huawei gear - and from who knows where - I don't really care.

I can't see what they'd want with my info. If I was working on stuff to be patented or something then maybe ...

If I use an Apple device the Chinese or USAmericans could be surveilling me; Samsung/LG, perhaps the Koreans; Sony/Fujitsu maybe the Japanese ... I wouldn't know either way, nor ever need to care AFAICT.

As the parent suggests, perhaps if you have a lot to lose then paranoia about this might pay off.
