IMHO yes, it made the rounds among the major tech outlets at the time. Although technically you could argue that everyone else was “reporting on bloomberg’s reporting”. It would be accurate but not reflective of how readers generally interpret these. They dont usually go “oh wow it’s interesting news that bloomberg is reporting this”, they internalize “oh wow supermicro has backdoors” instead.
