"Injustice" implies that someone else should have received the domain instead.
On what basis can you make this claim? Who else was more deserving? Some random registrant from another registrar? Did anyone "deserve" to get the domain?
If they have violated their registry contract or any laws, then they should be called on it: File a complaint with ICANN and the Federal Trade Commission or equivalent.
If you believe registrars should be prohibited from owning domain names, then lobby ICANN for change.
Otherwise, quit your whining and shut up. The system was designed for competition, not for "justice"
