Plenty of people use equity this way. Maybe not in your circles, but it’s not a new definition, it’s been around for decades. Millions of people in the US alone do not equate the criminal Justice system with the concept of Justice. Perhaps you should recognize that your perceptions are not able to be applied to the entire population. If you ever find yourself using “nobody” or “everybody” and you have no definitive data backing that up, I would recommend re-examining your biases, because what you appear to be doing is attempting to normalize your beliefs while otherizing the beliefs of others who do not share your view.
