It’s not that judges don’t care, it’s that courts are there to provide a remedy where one party has injured another. If there is no actual injury (damages in legal parlance), then the court has no power to provide a remedy.
Although just practically speaking oftentimes in these situations the expense of a lawsuit dramatically outweighs any potential compensation. Judges tend to view those cases as a waste of their time because the plaintiff is usually just trying to make a point or to punish the defendant rather than seeking meaningful compensation. It’s basically lighting a big pile of cash on fire to make someone feel better. Most judges believe the courts aren’t there to act as platform for grand standing or moralizing or punishing wrongdoers (at least in civil suits without punitive damages). The court system is already overloaded just dealing with more substantive cases where injured people need to be made whole in a significant way.
