I don't think determining legality and harm should be a boolean operation. There are layers of subtly and nuance in most things, and the law is one of them. I don't think posting the F word on a forum where the owner doesn't want you to post it should be treated as an equal violation of the law as deliberately abusing your competition as a billion dollar business. The amount of damage, and perhaps potential damage should be considered. When I swear a reasonable person would think the harm is minimal. When I try to sabotage another company where the damage could result in billions of dollars of lost investment and thousands of jobs vanishing a reasonable person would think that's pretty bad. They're technically the same 'crime', but they're obviously not the same in scale.
