“Sometimes it is unclear what is driving a litigation, and only by reading between the lines of a complaint can one attempt to surmise a plaintiff’s true purpose,” wrote Charles Breyer, the US district judge, in the ruling. “Other times, a complaint is so unabashedly and vociferously about one thing that there can be no mistaking that purpose. This case represents the latter circumstance. This case is about punishing the defendants for their speech.”
