Those claims were never confirmed, no? Some of it might be true or trueish but I'm not talking Bloomberg's anonymous sources word for it, and with so much supermicro gear out there you would think some other evidence would show up.

Bloomberg's claims sound like science fiction: https://www.servethehome.com/investigating-implausible-bloom...

Bloomberg's tech coverage is not great from what I've seen. Last year they published a video which was intended to investigate GPUs being smuggled into China, but they couldn't get access to a data center so they basically said we don't know if it's true or not. Meanwhile an independent Youtuber with a fraction of the resources actually met and filmed the smugglers and the middlemen brokering the sales between them and the data centers. Bloomberg responded by filing a DMCA takedown of that video.

Didn't that turn out to be incorrect?

Multiple security companies looked into this and found nothing malicious.

From thousands of miles away you can hear the fans at the NSA data center as they spin up checking the background to all responses to this posting.
