"On those two products we take the printed circuit board, which is just a blank board that has no components" Don't count on that. On Schneier's blog years ago, we brainstormed attacks on hardware in subversion discussions. One idea was putting a hidden chip in the board itself. Another was modifying the board's material to emanate secrets for RF attacks by a nearby attacker. There's a reason high-security at NSA required TEMPEST shielding. I wonder who prints the circuit boards. On the chip side, substituting one of them with the same covers would be an easy attack. One team showed a tiny change at analog level could have subversive effects with low odds of being spotted. I wonder how they verify they received the correct chips. Just from a domestic, manufacturing angle, the story sounds great. I'm grateful the company made sacrifices to make smartphones in America. I hope their example leads to innovation that drives the prices further down. "we are doing the entire manufacturing process of all of the electronics, meaning resistors, capacitors, integrated circuits" I disagree with this take unless the integrated circuits are designed and fabbed in America and by Purism. They're critical, high-value parts of the product that used to be piles of individual components before ASIC's. If not made here, I'd say upfront it's manufactured in USA "except for (percentage or function of) integrated circuits in it."
