Yea, it’s not C that is crap, but that it has zero guard rails. Like blaming a knife for not having a guard… Is it a bad knife without a guard? Depends on how sharp it is. The guard is orthogonal to the knife’s purpose, but might still be important when the knife is used.
Just because something doesn’t help prevent accidents does not mean it cannot serve its actual purpose well, unless its actual purpose is safety.
