Definition of "misanthropy"

Hence gloom and misanthropy have become the characteristics of the age in which we live, the solace of a disappointment that unconsciously finds relief only in the wilful exaggeration of its own despair.

1817, Percy Bysshe Shelley, The Revolt of Islam, Author's Preface

According to this saga of intellectual-property misanthropy, these creatures [patent trolls] roam the business world, buying up patents and then using them to demand extravagant payouts from companies they accuse of infringing them. Often, their victims pay up rather than face the costs of a legal battle.
