It's very much still a huge concern.
I gave my son a Huawei watch a few years ago for Christmas. I thought he'd be excited, but when he opened it, he frowned. I asked him if he wanted a different model and he said: "Dad, I can't wear this". When I asked why, he told me that since he works on highly secure missile systems at the aerospace company he is employed at, he would not be allowed, even on his leisure time at home and about.
After that, I was shocked when I went to a security conference in a US city that had an international pavilion. In that pavilion, there were numerous Chinese companies looking to sell security camera, face recognition, and cyber protection systems to American attendees. How any American company can purchase and use Chinese tech in security or cybersecurity systems is beyond me. After being around these issues, I'm not hesitant to think that China hasn't manipulated chip technology to spy on our iPhones as well...
