That's not quite the same thing.
Yes, someone can fork your project, but you maintain control over your own repository. Nobody gets to say "I need this, so you can't remove it or previous commits related to it from your repo". You can totally filter and scrub your own repos.

You control your own disk but by putting it on nexus you’ve put it into their repo and said others can depend on it.
