Distrust is a very strong motivation to reject a bid. If Boeing had won the bid, the NSA would have armed themselves with a FISA court order, mandating Boeing to install malware in the fighter jets, along with a gag order forbidden Boeing to tell Brazil. Due to their massive internal audit problem, the one or the other rogue NSA contractor would end up selling off a copy of the specifications describing the backdoor to crime syndicates, who would then be able to blackmail the Brazilian government. To cut a long story short, it has now become impossible to buy any American technology product which contains proprietary software or hardware. It must now all be open source and open design and then reviewed by non-American experts at the expense of the American company trying to sell its gear.
