I don't know if this kills the program for a decade. Yes, they are losing a lot of money. No doubt all of the revenue will be bled from the football program, because if the university cuts anything else because of this there will be serious complaints.
But I see Penn State fans and alums rallying around their team. It would not surprise me if the team generates more revenue next year than it ever has. I think the amount of scholarships lost is almost trivial (25 to 15??). You don't think they can find 10 players who will play for free? Or that some booster will find away around this?
Vacating wins is meaningless, since the wins happened, and no player who went against PSU and lost is suddenly going to feel like they won that game.
4 years of bowl bans? Nothing. USC got 2 for the Reggie Bush stuff. And they fielded a Top-10 team last year.
4 years from now, when they are back in bowls and making plenty of $$ again, the program will be back to normal.
