The US nationalists have been complaining for ages about "American jobs being lost to the Chinese" over the fact that US companies were having their stuff manufactured in China, so as to be able to cut down on production costs and maintain broader profit margins. Trump did exactly what the nationalists have been demanding for decades, and I see the Huawei spying claim as merely yet another lie from the US government. To the best of my knowledge, nobody has presented any solid evidence yet.
I own a Huawei phone, and I've kept it pretty stock. I've only installed Firefox as an alternative to Google Chrome ─ which does spy on us, and Google is a US-based company ─ but I don't believe it would be spying on me. In fact, it has very detailed permissions settings and it doesn't do anything that you've not explicitly allowed it to do.
