This third-game/redshirting thing is a concern to me, as well.
I will say for myself...college football is the only sport I really follow. I've never particularly cared for the NFL, largely because of how quickly the players move from one team to another (same for MLB, etc.) And well...here we are.
I've commented on the board in the past...I wouldn't hate it if we got to a point were 30 or so programs figuratively become a minor-league NFL, leaving schools like Northwestern, Iowa, Wisconsin, etc. to go back to playing a regional schedule with more modest talent. Maybe we play 10 games per season, we can pay $100 per season to stream away games, and at in December there's an FCS-looking playoff or we just make arrangements to play a final exhibition game in a destination city against a mutually agreed upon opponent. Players get their full scholarships and maybe a modest stipend based on revenue, which they all know won't be a fortune, and they don't mind.
All that would be just fine by me. Honestly, I would probably wind up donating more because I wouldn't feel like NU was just trying to exploit me like other programs do so effectively to their fanbases. Have you heard about the 10% "talent fee" Tennessee has added to its Season Tickets?
