Devil's advocate here... I would have hoped the opportunities were so lucrative that whistleblowers would have already, eh, blown the whistle. That's exactly the point of the whistleblower's protection laws.

So maybe these things aren't as widespread as you'd think... at least not in a legal sense. I'd also like to think that maybe people aren't "designing" flaws into things rather than finding the maximum economic benefit, or just are "naive" to what they design.
