I'm sure there will be litigation over the Bloomberg story
To make such damming claims without a shred of physical evidence leaves Bloomberg in a very bad light as well as legal position. If there multiple sources were accurate you'd expect them to be able to at least produce one compromised mobo, pictures of the compromised mobo, data logs of the mobo transmitting improper data or some reasonable irrefutable evidence to support their claims. Absolutely no one involved be it the companies or the authorities are supporting the Bloomberg story and in fact it has been denied by all parties. I'd expect Bloomberg to be served before the end of the year for damages and possibly malicious criminal fraud.
