A couple of years ago Bloomberg reported about spy chips/hw backdoors in SuperMicro mainboards but to my knowledge without a smoking gun proof. Maybe they had to settle outside of court and also had to sign papers to help protect the company from further damage in the future. Using (other) Bloomberg material may have triggered this. Of course this is a wild speculation. I have no evidence or insider knowledge.

Yeah what as the story behind the BBerg take down drama? I just remember it being something absurd.
