This doesn't matter if you don't have the millions set aside to defend yourself in court against a giant conglomerate. Giant companies breaking NDAs with scrappy startups is a story I have heard often.
If you blatantly ignore and NDA, and then make a lot of money from it, then the 'small startup' will have a ton of money because the prize is huge, i.e. a % cut to lawyers who can work pro-bono.
Imagine you have a $10B company and some bonehead PM steals info from some small startup, for some stupid small project - it puts everything at risk.
In most case, I think you have boneheaded actors, usually not acting in the best interest of the company.
