If we were to outlaw NDA's and dramatically beef up whistleblower protections for corporate whistleblowers, that might work. But those are wildly implausible proposals! And while people are bad at keeping nefarious conspiracies secret, they're quite capable of keeping quiet in general - which happens to protect the less egregious but more relevant kind of grey-area, pushing the boundaries that slowly evolves. Just look at all kinds of corporate and governmental malfeasance stories to see that it's pretty normal for ethically dubious behavior to go on for years if not decades before it comes out. Most of it probably never comes out. People can't keep crazy conspiracies secret very well, but are completely capable of keeping eroding standards quiet.
