3. Customers want to do something, you help them do it, and nobody has done it before, so whether it's legal or not is kind of up in the air.
E.G. Uber exploited a legal loophole that distinguished the kind of taxi service you hail on the street from the kind of taxi service you call on a phone.
The latter were much less regulated, and usually much more exclusive and pandering to a richer crowd. Nobody really knew which kind Uber should be classified as, it was the first kind in practice (same customer base as normal taxis) but the second in theory (ordered, not hailed).
It is clearly different because in one case you are not guilty of fraud.
Being guilty of a crime plus fraud is obviously worse than just being guilty of the crime.
Breaking the law by stealing a loaf of bread is obviously different to killing one million people but "both boil down to breaking the law" - I'm not sure that comment contains that much information.
1. Customers want to do something, you help them do it, but it's illegal.
2. Customers want to do something, you tell them you did it, but you were lying and defrauding them.
