I think it's a mistake to underestimate just how much native R&D goes on in the broad and deep ocean of China's modern manufacturing complex. That entire industry has been working hard for decades now at learning from its customers, continually seeking opportunities to "level up". The particulars of this specific, sketchy case aside, the idea that Foxconn hasn't invested in sophisticated R&D facilities at this point in the game is far less believable to me.
