If you created a shell script that did this, and put it somewhere in your $PATH, I'd agree with you. But this guy did it as a shell function. This means that it only takes effect in bash shells. And if he loads functions correctly, then it would only take effect in login bash shells. This restricts it to only interactive use, exactly what you want. It no longer affects scripts and other tools.
