There’s an easy way to do this. Buy out the contract.

Companies offer foolish lifetime packages all the time. I think it was American Airlines offered lifetime unlimited first class flights. They can’t claw this product away from the few remaining die hard users, and they only sold a few dozen of the things.

I expect the reason for wanting out of the deal is the same.

Airline seats and supercharging time share a scheduling problem. Having even a few customers with unlimited rights to a limited resource creates intractable scheduling conflicts.
