Sarcasm aside, I don't see how the existence of this code or its hypothetical adoption would hurt anyone. Ideology isn't worth following for its own sake, there has to be a mapping to physical reality, and any mapping that interprets a rewrite of coreutils as bad because it's too permissive is extremely suspect to me.
Like, what does the GPL infectiousness even protect here? Coreutils is decades old. Are we worried Microsoft is going to EEE it?
