There's no cap on what the committee is now considering "legitimate" NIL opportunities. The kicker is that those opportunities now have to be what you'd consider as fair compensation for selling your "name, image, or likeness". That is, what would the market bear for you appearing in an advertisement, promoting a product, or marketing T-shirts with your face on it? There's an accountant clearinghouse that's required to validate all opportunities over, I think it is, $500 or so.
Compare that to the "collectives" who gathered money to donate to players in the name of supporting a charity or some such. In these scenarios, everyone knows the players aren't actually appearing in legitimate advertisements, and that their association with this business (non-profit or otherwise) is nothing more than a paper referral to gain a payment. Usually, these charities, while complying with IRS guidelines for donations etc did nothing more than pay players. The NCAA lent its blessing to all this.
