Today's China is a technically very sophisticated country, but just as with its sophistication, its shadow side has become amplified, and they have become Huxley's "Brave New World", or ─ ironically ─ the Romulan Empire at its worst. The irony is that the late Gene Roddenberry did actually create the Romulans as a metaphor for Communist China, and that they seem to be headed for exactly the kind of society he predicted.
Are you so certain of that? All I know about it is that those claims were made by the Trump administration as an excuse for a trade war, and that in itself is already shady enough.
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.
