When David is just a nobody, and Goliath has all of the legal and PR resources in the world, Goliath doesn't even have to swing a punch. Goliath can just drive them crazy with social and legal pressure. Also, David might have been a bit of a decision-making outlier to begin with, being the kind of person who decides going up against Goliath is a good idea.
I work with a relative who is in the real estate space here in India and often deals with land shark mafia. The biggest thing I learned from him, to win in these situations is don't fear or not be afraid of consequences.
You need to have ice water flowing in your veins if you are about to mess with something big. At worst you need to have benign neglect for the consequences.
Often fear is the only instrument they have against you. And if you are not afraid, they will likely not contest further. Threat of jail, violence or courts is often what they use to stop you. In reality most people are afraid to go to war this way. Its messy and often creates more problems for them.
