I am not saying cheating is fine, all I am saying is that it is not as rigid as rules in mathematics. If we are just talking in strict theoretical sense, sure, all cheating is bad. But life doesn't work that way. This is why we have courts and judges and lawsuits.

My guess is this (based on nothing but personal opinion) - most people would say cheating is bad, but the same people wouldn't be surprised at rampant cheating that happens around them. They may themselves even cheat, if they get a chance. Whether we like it or not, cheating happens all over, so people are just used to it.
