I personally do not trust China, should we not assume computer hardware made there has invisible backdoors? The security state for example believe 5G shouldn't be controlled by Chinese companies, I'm certainly not sure I really trust what I say on this MacBook Pro, is there a way to prove it's not compromised as everyone says it's definitely not but I can imagine the Chinese suddenly just switching off half the computers in the West in the case of a war one day (say the US defending Taiwan). If I was them looking to become top of the hill I'd be instructing people at Foxconn and wherever else to provide me with backdoors into most computers sold in the West.
