IIRC the California legislature set the NIL trend and other states soon followed suit. The NCAA has taken a hands off approach, no stomach for further litigation I guess.
As I recall it and I could be wrong the recent Supreme Court decision some reference was specifically regarding total cost of attendance, not NIL, but in his addendum beer guy Kavanaugh signaled that attempts to limit compensation whether third party NIL or direct payment might not pass mustard if it crosses their desk.
The NCAA punted on this, pure and simple. Picking their battles. If you like NIL, realignment, conference collapses you’ll love what’s next. Legislation proposals enabling employee status, bargaining power, work stoppages. Hold on to your hats.
