I have a friend that is a minor celebrity and has controversial opinions and thus has been sued a lot (mostly frivolous, one or two semi-legit) and he will straight up tell you: the winner is the person with the most money.
If one party has deep pockets and the other does not, the rich guy wins. He can drag things out in court forever making it cost more than the small guy has to keep going. In the end so much is subjective anyway, and the high priced lawyers will get their way.
