This is a great point, and reasonable people can disagree about when an application's abuse or potential for abuse crosses the line. The same goes for pivots or for general-purpose code that's used elsewhere. (Is it ethical to contribute to internal tools at Facebook? What if those tools make other engineers way more effective at doing things that ultimately undermine democratic systems?) My point here isn't to dictate what software is or isn't ethical, but to argue that if a program is unethical, its ethical implications are the responsibility of the engineer(s) who wrote it.
