I believe the Bloomberg story because of their report that the malicious chip was originally found on hardware owned by Elemental, which at the time was a small startup company that had government clients. The hardware was found when Elemental was acquired by AWS and they did a more thorough hardware security review. Elemental would have been a good target because of their government clients but was/is not large enough to be noteworthy otherwise. This is where I trust the Bloomberg story. Saying, "Amazon, FB, Apple got hacked" is one thing. Including a then-200 person startup company in the mix is another. To me it serves as evidence that the hack was real.
