seems like physical evidence would prove this story. Has anyone other than supermicro's 3rd party auditor xrayed the chip in question?
No suspicious chip was ever found on a Supermicro board.
The story is fabricated, and it's impossible to check because all there is are rumors from unnamed sources.
The story was so good that everyone wanted it to be true and nobody said that it looks like an incoherent mess.
Which is totally possible, but normal journalistic practices already exist to prevent just what you suggest, and are the norm, not the exception.
