I'm not sure that this "story", adds up, in my mind.
Because the journalist(s), who released the "story", seem to be claiming, the main evidence comes from Amazon, Apple and SuperMicro.
Yet, Amazon, Apple and SuperMicro all strongly claim the story is nonsense.
The journalist(s), explanation of why, Amazon, Apple and SuperMicro all deny the story, is because (they are hinting), the US Trump Administration has gagged them.
But, if the US Trump Administration has gagged them, why have the journalist(s), been allowed to release the story.
tl;dr
This story sounds very fishy and doesn't seem to add up.
I get, very suspicious of the US Trump Administration. Especially as regards, honesty and integrity.
Recently, Trump has been VERY aggressive against China, at the UN and with Trumps massive trade war with China.
This makes me very suspicious the story is false (or exaggerated or something).
Where is the real evidence (i.e. hardware) ?
Let's see these spy chips and let independent organisation(s), investigate them and publish the results.
