I was wondering about the consequences of breaking the restrictions, e.g. how severe are the penalties? I would love to read that as a headline in a newspaper "US Gov. sues free education provider for educating people in x".
wikipedia's not the best source but from my limited experience this is in the right magnitude, with the key thing being $55k per violation. That can add up quickly depending on how its interpreted.
Criminal penalties for violating the embargo range up to ten years in prison, $1 million in corporate fines, and $250,000 in individual fines; civil penalties up to $55,000 per violation.
