Yes, and article starts out by definining manufacture as "assembly using more advanced tools than a screwdriver". They solder. Good for them. They keep mentioning that their resistors are made in the US. That's great, but not unique to them.
They don't manufacture their important components. Not even Apple does that. No one does. There is roughly zero chance that any of the non-interchangable bits, the SoC, the battery or the screen, is manufactured in the US.
And there is nothing wrong with that. It's just silly to pretend otherwise.
