It feels like you're making a bad-faith argument here. You can implement 'yes' in a straightforward way in a couple lines of C, too.

  main(int argc, char** argv) {
    while (1) {
      if (argc > 1)
        for (int i = 1; i < argc; i++) printf("%s%c", argv[i], (i == argc - 1) ? '\n' : ' ');
        else puts("y");
    }
  }

The point other folks are making is that it's written differently for a reason. Maybe not a reason that's important, but at the very least, let's try to compare apples to apples.
