I remain to be convinced that Apple or Samsung are any more trustworthy than Huawei. It's all made in China. While these manufacturers may not be sneaking backdoors into devices, since this might be caught, they likely are being compelled to disclose designs to be analyzed for weaknesses. It doesn't really matter if some of the design work is done in California.

I wouldn't have substantially higher trust in something made in the U.S. or other "five eyes" countries either. These governments do not respect the privacy of their citizens, as evidenced by the NSA's recent breaches. Some countries do slightly better than others (e.g. Canada probably isn't as bad as the U.S. yet). However, on the whole, privacy rights seem to be on the decline in these countries. Treaties and cooperation between the security agencies of these countries drag everyone down to the lowest common denominator.
