No need for that much tinfoil, this came in parts straight from the Pentagon [0] and Bloomberg's "specialist", Tavis Ormandy, turned out to have a vested interest in selling "cyber security" related products aimed at supposedly fixing exactly these kinds of supply chain problems [1].
Imho The Register also points out some interesting details about this whole thing [2]
It's not really that surprising, fits perfectly into Trump's narrative of "They took our manufacturing, it's time to take it back to the US!". Gotta start somewhere, telling everybody China is selling a lot of bad apples seems like a simple enough start.
Do you mean someone else rather than Tavis Ormandy? As someone else has already pointed out, he's at Google Project Zero (which isn't in the business you describe) and I don't think he's ever worked for the company whose brochure you linked to, and so far as I can see he's been pretty rude about the Bloomberg story.
