It's amazing when you think that EE is such a monster of a discipline that there is such a lot of loose terminology used, even at high levels by some people.
The alternative is to have language police censoring stuff. Physicists do it. Consider what happens when someone uses the phrase "relativistic mass" here on PF in a physics. If they keep policing that for another century or two, the depricated uses will disappear.
But we still have Newton's Laws but only Einstein's Theories. My favorite are principles. A principle is true because it is a principle.
