The first photo shows that the portion of the anchor bolt that secures the brake wire is precisely where you'd want it to be---it's directly in line with the cable housing stop in the supposedly bent brake arm.

Thus, unless you're all seeing something that I'm not seeing, and factoring in the previous comments acknowledging how unlikely it is that damage or miscasting was involved, it looks as if the bend in the arm is intentional, i.e., represents a (reasonable) design decision.

But I imagine that the discussion will continue regardless.
