I saw some articles implying that they thought so too but are actually using a lot more Chinese components even as substitutes for military grade components. Given that the portion of US companies make a military and commercial grade component with only thermal differences, I would wonder if they aren't getting a lot of commercial grade versions of US designs from China.
It would be interesting if someone goes through their wreckage strewn about and starts to catalog the finer details of some of the small components.
