There are 3 big issues
1) Technically the chip can't do what Bloomberg said, that is the opinion of me and 49 other engineers at work, we all had to read the article completely and prepare a document about the feasibility of it occurring for our New VP, who called an emergency meeting Monday morning after reading the Bloomberg article to be sure we didn't have one of those Supermicro servers. I have refrained from calculating how much that effort cost us financially, and I know its happened at alot of other companies even just in town here.
2) Given the story as Bloomberg has posted it, Tim Cook and Jeff Bezos has to know about it. Given their strong denials, which are HUGE SEC violations, we have to assume that either they are both tired of their jobs and want to be removed from the Board of Directors of the companies and fined 10s of millions of dollars each, or the story is not true. I don't believe Jeff or Tim want to lose their jobs or pay big fines, so the story isn't true.
3) The trail of Apple replacing 7000 servers in a few weeks per the story would be so easy to find, and there is nothing about it, in any trade, annual report, etc, I've dug through them since the article. That is alot of money spent by Apple and alot of money received by some vendor and there is nothing out there. If there was it would be trivial for Bloomberg to show it. As you can you see from Apple's annual report 2017 page 32, Apple had to buy 7000 servers, replace 7000 servers etc then Apple would be trying to explain that, or they could point to IBM, HP, Dell delivering 7000 servers to Apple, but there is no such support and so Bloomberg either wants us to believe that two or more companies are lying in their annual reports, or that 7000 servers are so cheap its in the noise region. Also we get leaks on all kinds of things at Apple, how does the effort to replace 7000 servers scattered all across the world, not get us one rumor.
What do I think happened? A couple of years ago Supermicro shipped a board to Apple with an infected driver, we know that happened, Apple told us about it when it happened they found it in their lab before the computer was put to actual use. The response to that (which Apple wasn't happy with) and a better price from another company is what led to Apple to cancel any further purchases from Supermicro. Someone thought the infected driver was a chip (as in a USB driver chip) instead of firmware which it really was and the theory was born. Supermicro lost an order of 1000s of servers from Apple, and suddenly Apple has removed 7000 Supermicro servers for the problem according to Bloomberg. If any of the stories on counterfeit parts served are part on this story, I might be one of the 17 sources, since I am definitely not shy about counterfeit parts likely coming from China, but counterfeit parts are a totally different thing. But the whole article is technically inaccurate, so why would you would be surprised that the sources are quoted inaccurately. Bloomberg says that x-rays of the boards and the parts exist, but yet have yet to show them to us. We literally get pictures of the inside of the new iPhone and its new processor within days of it shipping, yet Bloomberg works on an article for 18 months according to them, and yet can't put a picture of the chip or the board in question into the article. Also its very interesting that Bloomberg is blaming none of the Big Three for making these boards, but instead blaming 4 factories which I and others are pretty sure can be tracked to one now nonexistent company. So its kinda like saying Toys-R-Us made the boards in question, aren't going to get sued by a company that doesn't exist anymore especially if you don't specifically mention them by name.
