"Why does no insider disclose the non libre computer software?" "Who, how and how many guard the secret parts of software on hardware?"
1. If there's something illegal in the *ware : The insider must disclose it. It is a duty, both ethical and legal, to dennounce the violations of people's rights. Otherwise the insider becomes a collaborator for the ongoing crime, and will be punished for it should it be discovered.
2. If there's nothing illegal in the *ware: The insider mustn't disclose it. We are not copyright infringers here. We want free *ware, not *ware for free. That means legally free *ware, and the way to get legal alternatives to non-free *ware is called "the clean room". Team A studies the non-free *ware and makes a detailed list of features. Team B programs new *ware from scratch to implement all the features without knowing at all how the non-free *ware implements them. That way the new *ware is original, and legally free. A disclosure of the non-free source would only get in the way - not only there's no need for it, it could even provide a legal base to compromise the free *ware legitimacy.
