So what if he asked friends/associates who are lawyers for a quick feedback, or even paid the lawyers for limited amount of time? When a lawyer gives you a quick assessment and it's "This is very risky," how likely is it a more thorough review of the contract will be more positive?

Considering DJI's position at that point was "this is a final offer" how useful would it be to shell out a considerable amount of money for a more thorough review?
