Raasch is not saying that sore ribs aren't good for a pitcher; he's saying (somewhat poorly) that the stress on the ribcage caused by pitching makes it harder for the fracture to heal. Had it been just the bruising like they originally thought, it would've gone away on its own. The fact that it didn't go away led them to look closer at it, whereupon they found the fracture. It then became a decision between shutting him down now and letting the rib heal quicker without stressing it, or letting him pitch through pain and having it take longer to completely heal. It would've been pointless to ask him how he felt after pitching. When you've got broken/bruised ribs it hurts to breathe, let alone pitch. Everyone handled the situation correctly. Nobody is the problem.
