I know Waid didn't raise as much money as Meyer, but he still was funded for tens of thousands of dollars. So he had a decent war chest of his own to defend his pride before having to get into personal costs.
Also, as far as I know he doesn't have dependents, unlike Meyer - only a roomful of expensive toys. Plus didn't he just sign up to do some new, high-profile work? Hasn't he been working steadily this whole time? So while this might end up actually biting into his revenue, Waid has shown himself to completely be the kind of man who would rather destroy everything he has rather than grant his enemies anything.
The smart play would have been to apologise and settle, but Waid doesn't think he has done anything wrong - in this case, or likely ever. So off to court it goes, where I suspect he will fight as long as he can to never admit any wrongdoing.
I do so hope he melts down in court. There's nothing he could do to lose the supporters he has who are just as much the narcissistic zealots he is. But him having a King Baby tantrum would be fucking hilarious, almost as much as him publicly getting BTFO and not getting his way. Which will be the court's fault, not his, of course.
