How's this any different from any other Made in China electronics product?
EDIT: The replies are aligned with what I was thinking: If anything, Foxcon is above average in factory conditions. The major reason for the Apple focus is because of its high visibility.
I despise this easy targetism! I felt the same while watching Supersize Me, which focused on McDonalds, and some of Michael Moore's films. The basic premise may be correct, but selecting targets to ride on their name (McDonalds, Walmart, Apple) is an easy tactic and in fact puts off the critical thinking people who resist the manipulation (well, at least it puts me off). And what's more, in most of these cases the (more naive) audience is led to believe that the situation is this specific company's fault, leading to behavior like "Man, I'm never gonna eat another BigMac, will go to Burger King instead".
