If this was sorted that greatly by you, why are you doing your best to cover everything up?
A business operating within morally acceptable borders doesn't push it's customers into signing some wicked NDA (I suspect that's what happened with jason).
Or how can you explain that he is not willing to share details about his settlement when he initially was so open about sharing this situation?
Why does he say "I can't tell more" if not because you made him shut up?
