I have a feeling the majority of this research is conducted by Five Eyes military counter-intelligence branches (ripping it out of the hands of whoever was on the trail before), with the resulting reports passed around in redacted form to those who need to know (e.g. the manufacturers, suppliers, investors, etc.) but not generally bubbling up to the public, except through backchannels (like my friend in the Navy who warned me ten years ago to avoid buying anything with Huawei chips in it, saying he couldn’t get into the details.)

If the current approach is more of the same, we’ll see these reports declassified in 30 years or so, when China is (in one way or another) no longer the same looming threat it is today.
