You're arguing with a strawman you created, no one made any statements about the author.
The original comment called it stealing. There's nothing morally wrong with stealing, but regardless it's not even stealing. It's a stupid argument.
Solid justification for using it for coreutils you got there...
I'm obviously talking about not giving a shit about how people use it. Which makes sense for coreutils. Loads of people use it for loads of different purposes. The author shouldn't care how people use it.
