Seems pretty straightforward to me. If the customer set the agent in motion, the customer is no less responsible for the damage than someone that (as i think Cal Newport said) ties a weedwacker to a dog. It’s reckless.

If they were sold a product that claimed to be safe, they could in turn sue whoever sold it to them. Jeep’s insurance wouldn’t pay someone I crashed into because of defect in my jeep, but I could in turn sue Jeep for my legal trouble.

For example POLi. If you pay by giving your bank creds to POLi and they steal your money, you can't sue your bank but you can sue POLi.
