I should add "under california law". But it's very hard to prove anything, and whether you end up winning or not, it's expensive. Of course there's nuance there, but in the case of "Hello contractor, I've got an idea and I want you to sign an NDA for me to tell you about my predictive analytics solution", unless the contractor literally steals the name of the company and weirdly specific plans you provided in writing, there is no case. And even if there was a case, do you have tens of thousands of dollars to chase it? Is there a famous case where an NDA became a key factor? I think Facebook would be the one everyone thinks of, but that wasn't a case of an NDA, there was a lot more going on there. But if Mark had just said "Actually, I'm severing any business relationship and starting an entirely new codebase, company, etc. by myself" he probably would have been fine. Especially in California.
