There might not be a personal consequence directly attached to Amazon employment, but this certainly has impact from a career standpoint. Mentioning the manager could inhibit him from further employment elsewhere, because once the HR Depts of other companies' start to gather background information on him, they'll think he's a whiner fingerpointer. You cannot exclude a person from employment just for that, but they'll find another reason to not hire him. It doesn't drive change at Amazon, but it saves him unnecessary risk.
