Something to remember is that litigating at every opportunity, even when you have a losing case, is not always best for a cause. The only way that something big is going to happen to the WTS is if public opinion turns against them. When members of the public or the court system who don't have an interest one way or the other see outlandish claims, a flair for sensationalism, or a personal vendetta, they tend to think that the person or group making those claims is the problem.
Historically, groups that have been successful fighting in court for rights that are unpopular or lack public support pick their battles very carefully. They are well-organized and resist the temptation to pick fights that could be damaging from a public relations standpoint. I think it's important to realize that even though someone might be fighting hard for your cause, they might be doing more damage than good to it.
