The vast majority of civil cases are settled out of court. This is very much encouraged as it keeps these cases from clogging up the overburdened legal system. Courts exist to enforce the law, not as a forum for people with 'deep pockets' to pursue personal vendettas. So if a case can be settled without burdening the publicly funded legal system, why would William, or anybody else, not do this?
I don't doubt for one second that the same people complaining about 'Willy' 'pocketing the money' would be whining about him wasting public resources if he had gone to court rather than accept a settlement.
