They would have to hedge, "we are investigating Bloomberg's allegations and take security seriously."
You either anger govt that is authoritarian & capable of confiscating your entire production (basically ending your current business)
OR
You make some half-truth statement (not necessary to be lying, but that does not change the point), and - if everything will be revealed - one agency of democratic govt will be pissed and slap you with big fine.
Basically this is big enough to make SEC meaningless.
The SEC on the other hand literally just got done fining Elon Musk $20m for a tweet. Fines for something like this could be in the hundreds of millions, that's not something you risk when you could just say "we are investigating the claims and take them seriously."
It's such obvious damage control in shit-has-publicly-hit-the-fan situation ... Why do you think SEC's fines (lol $20M, even for Tesla/Musk it's not a big deal, Apple would have to be hit with 100times that to even notice it) are even relevant now?
And "It isn't going to happen." could have been said about hardware attacks on USA from China last week. Situation has changed quite a bit, China is either starting to abuse its hw monopoly or someone is doing A LOT to prevent such scenario, so the stakes are too high for simple SEC fines to be worth discussing.
Publicly traded companies do not have the same freedom to lie because the truth or falsity of this claim has a direct impact on their stock price. Something we just saw with Musk less than a week ago.
> "Our best guess is that they are confusing their story with a previously-reported 2016 incident in which we discovered an infected driver on a single Super Micro server in one of our labs. That one-time event was determined to be accidental and not a targeted attack against Apple."
They deny Bloomberg's specifics, but basically admit that the general attack vector very much works.
