And what would he stand to gain by becoming an adult "tattle tail"? Even if him doing so would start to bring about the change you mentioned, he'll be out of NCAA competition by the time anything is ever done about it, if at all.
On the other hand, he might have something to lose, and that's the respect of the athletes he competes with. They are all getting paid more money than they probably otherwise would by taking advantage of this "tampering". If he helps stop it, and keeps players from earning more by transferring, I'd suspect he might take a hard foul or ten per game. Look at how Caitlin Clark is getting beat up in the WNBA - I'm not sure why, but she must've done something to someone.
