I'm simply saying the B1G is in a position where it has no choice but to respond or concede, and the only realistic response is ND+USC and friends. There really aren't any options other than doing nothing, falling behind competitively/financially, and tOSU/UM ending up in the SEC super league someday. If you take the top 4-5 properties out of the P12, it basically nukes the revenue for whoever is left (plus the B12 contract/inventory, that would be greatly reduced) and that gets re-distributed to the next B1G contract. Keep in mind a move like this would basically consolidate all valuable non-SEC CFB content (outside of Clemson/FSU basically) to the B10 contract, and right now you could assume Fox/NBC/CBS would all be interested bidders - you'd want to confirm that before making any moves obviously.
It could be that ND/tOSU/UM are planning on joining a super league where they'll be the northern outposts in a southern conference someday, I would think they'd try to avoid that if they could, not sure how they'd view that to be in their best interest, but doing nothing here probably results in that over time as the SEC revenue would dramatically outpace the B1G revenue, as we seem to agree. If the revenue is close, tOSU/UM wouldn't ever put themselves at that kind of disadvantage, but given what the SEC just did, they're going to pull well ahead if the B1G does nothing.
If you're an attorney and know how you can get the ACC schools out of a GOR prior to 2035 cost effectively, my opinion on that would be different.
