Not a "cop out". I've been using something for 30 years; I'm going to continue to use it in the same way. They can go suck it for all I care. We in the industry know what we mean when we use the terms; I don't care what they do or don't know or want. I don't recognize it as being any of their business since they're "johnny come lately" to it.
