That suggests an interesting business model where: we sell everyone on 'Unlimited', then we wait to see who is the most egregious customer, and drop off the ones on the top of the pyramid (and keep the revenue positive customers).

Reminds me of how the cellular operators used to be towards roaming: sure, you can roam, just don't do it so much that we cancel your contract.
