This is pure fiction though. How many people read an app's ToS? If a carpet cleaner showed up with terms like: "I'll shampoo your carpet every month if you let me read your credit card bill every month." no one would read it before signing either, but I suspect that a court would also consider this contract unenforceable.

In addition, with software "contracts", it's often a case of "give an inch and they'll take the mile". The terms are always open to unilateral change from the vendor. So it's more like: "I'll shampoo your carpet for $50. And I can change the terms to whatever I like at any point in the future." which in itself seems insane.
