Unfortunately, when a settlement is reached, most of the time there will be a Non-Disclosure Agreement (NDA) signed, which prevents the plaintiffs from disclosing anything. This is a major incentive for the defendant to settle. In fact, they may even state that the defendant admits no wrongdoing in the settlement. Therefore, anyone else who wishes to pursue legal action against the defendant needs to have their own evidence. I believe this is a significant reason driving market participants (MMs) to settle.
It's important to remember that NWBO's primary focus is to advance cancer treatment technologies; it is not their responsibility to expose bad market practices. The Securities and Exchange Commission (SEC) is responsible for investigating and taking action against market misconduct.
By the way, you seem to have used 'plaintiffs' when I believe you meant 'defendants.'
