I definitely agree when he says threatening lawsuits just makes you look like a bully. Violence can be defined¹ as a measure taken to force an unwilling person to change their behavior. Based on this understanding, I think lawsuits are a form of violence: legal violence.
It takes real maturity to deal with the company the way they did. "Yeah, we're infringing your license, what you gonna do about it?" is a direct challenge that invites litigation. Clearly unacceptable behavior from a company that knows and admits its own guilt and uses its own impunity to make the developers look weak. Instead of taking them on, they worked with the company and convinced them to cooperate. I think that is a major example of constructive behavior.
