Okay, how about this.. and this HAS happened before.
My parents have a cable line coming into their house. They pay for BASIC programming. Nothing else such as HBO, Showtime, or any other extra pay to watch channels.
One day, lightning hit the big green cable trunk outside the house and burned out ALL the filters on the line. It wasn't their fault lightning hit. Because of that incident, they started to receive every single channel despite them not paying for it.
By law, THAT IS STILL STEALING. They aren't paying for the service, and it accidently got available to them. However, by using something they shouldn't be they are by law stealing. Yes, it would be simple for the cable company to come out, inspect, and replace the filters and thus stop my parents from receiving illegal programming. Or they could just shut it off entirely and refund any paid for but un-used portion of service. Just because it's a simple fix for the cable compan doesn't make it the cable companies fault, or gods fault, or natures fault, or something elses fault for abusing an accident. Only the person abusing the accident, even if they claim ignorance, is at fault.
This is the exact same scenario with the only different being it is dealing directly with a company instead of an individual.
Sorry, thanks for playing but you lost this game. Ignorance of the law does not entitle you to protection from the consequences. Just because you don't know your are stealing, or trespassing, or doing something else to break the law doesn't mean you aren't breaking the law. It is YOUR duty to make sure all your actions are in life are legal ones. It's not for someone else to babysit and protect you from making mistakes.
