It's such a strange and unfortunate addition to the project. Also, what's the point of assuming every entity is potentially hostile? Can't you just put in the license "you're not allowed to be malicious or hostile on this network"?
That's still a restriction on freedom. Some people's notion of malicious might disagree with the author's.
Just read the manifest.
GP used intentionally hostile and weird interpretation of "if you intend to subdue, enslave or kill, don't use it", aimed at dictatorships, organisations like Palantir, etc.
