IMHO, it appears that what Terry Childs failed to see is that the computer-communication network is not his to lockout. It was paid-for by the San Francisco taxpayers, and they entrusted (through elections) the city officials to manage the network, no different than entrusting these same officials to manage the rest of the city's infrastructure.
I believe if Mr. Childs truly believed that he was the only one who can manage this network and that his superiors were incompetent, he could have just been a whistleblower and filed a complaint to the state auditor's office (preferably with solid evidence of the risks to the network). He could have even gone to the news media as a last resort. However, he instead decided to behave like a criminal and perform reverse-hacking to lock everyone out. Pretty sad indeed.
