I assume the CMU folks didn&#x27;t break into any one elses nodes. It seems like one of the principles of Tor node operation is that you can run your nodes however you want. I don&#x27;t think there is any binding agreement or even strong implication that someone operating a Tor node agrees to not be hostile to users.<p>Perhaps it was unethical by the standards of university research, but I wouldn&#x27;t be bothered by the government doing this. If the government or a university researcher idled in your irc channel and logged the communications I would think that was okay. I kinda view this the same way.
