> internally designed boards

What? The allegations are against super micro boards produced in China.

Super Micro builds custom designed boards for other businesses given the right quantities. It's a huge part of their business; I wouldn't be surprised if it's bigger than their white box boards.

One of the allegations was that special purpose video encoder boards from a hardware startup that Amazon acquired (Elemental) were targeted. These aren't off the shelf boards that anyone can buy.

Because the sources in AWS and Apple who reported this issue to Bloomberg have access to the boards they're reporting about?

What details and evidence about these boards have these sources provided to Bloomberg? Are there any details or evidence?

Not if they've been destroyed or handed over to the authorities.

"It should be taken as fact because I can't prove it."

How about no.

No, just that the a absence of evidence isn't the evidence of absence.

There's next to no way that Bloomberg's sources would still have access to the boards, and that should be considered given all of the calls here to see them.
