Re: "Huawei is a private-owned company, nothing to do with the Chinese government.."
Have you studied the history of (say) the British computer industry. In 1970, you could have written
"ICL is a private-owned company, nothing to do with the British government."
People would have laughed very loudly. To quote Wikipedia: "ICL was an initiative of Tony Benn, the Minister of Technology, to create a British computer industry..." It didn't work out, but that's beside the point. All this is business as usual: of course the Chinese government supports Huawei, but that doesn't mean they control it.
