Ultimately, it's free market at work. Disney is only going to grab a contract if they can turn around and sell it, and/or it's going "below market value."
So sure, Disney would exercise refusal if there was 1 AKV contract for $102 per point, and all the others going through the system were $125...
But when you have a flood of low cost contracts, most will get through.
I have to imagine that there is increased re-sale supply and decreased demand. International owners have no idea when they will actually be able to use their points again, it could still be a couple more years. And even domestically, you have plenty of people who aren't ready to go to Disney right now, so they may be looking to sell. Meanwhile, the buying market has to be soft.... buying something that you don't really know when you will be able to use.
It's basically a great time for current owners to add extra points with a re-sale contract... Or even for an educated new buyer, who can be patient and think long term.
