"Can't prove a negative."
In the opposite case, even if this article is full of inaccuracies, judging by the discussions of security specialists, the scenario indicated in the article is quite possible.
The Bloomberg article described them as looking like 'signal conditioning couplers" on the motherboard. There is no such part on server boards but maybe they meant optoisolators or power conditioning capacitors. The former is a hard place to tweak the BMC from without a high probability of crashing it. The latter doesn't touch the data lines at all. They also quoted someone describing such a hack as being "like witnessing a unicorn jumping over a rainbow." I agree.
