Why are people even arguing about this? Is there some religion that forces people to only believe in and use GNU tools that they can't appreciate a competing tool? A tool's a tool. If it's useful to you, use it. If you don't need it, then don't. Why does this have to turn into a debate about why someone shouldn't have invented another tool because one already exists? Look around the world, there's competition and choice in literally everything. Why can't they be choice in what CLI tools to use?
