Why Babolat warranty replacement policy of racquets suck?

My kid found his racket was cracked while under warranty and when it was submitted for replacement, babolat claimed they couldn't since the frame fiber has been exposed. It was actually had been exposed very slightly and hard to imagine frame loosing strength over that. Do other racquet manufactures have a tough policy on their tennis racquets? I will not be bying Babolat tennis racquets in the future.
