They could be sued in small claims court.

Here that means no lawyers, no discovery, $100 to file in plain language, and a company employee (not a company lawyer, or a contractor, or a temp employee) must attend or they default.

$15k damages.

Reasons it could happen? Imagine grandpa has a tech come out 4 times, because his network is super slow. EG, this thing pounding his wifi for its scans.

Small claims court in the US typically requires actual damages, and doesn't add punitive damages.

Grandpa gets reimbursed for the four techs who came out, that's it.
