Yes it's wrong, but it is also reality. Just like when I showed you dozens of links to HVAC contractors and other "insiders" referring to "freon refrigeration". Just because *You* have defined it as wrong, does not make it so, nor does it make it go away, right or wrong.
I said freon is a compound. You say it's only a tradename. You say in the industry that *nobody* uses the name generically. I show dozens of examples of people in the industry using it in that way. All I have to show is *ONE* usage in industry to throw your "nobody" out the window. That's the problem with phrasing things in absolutist terms. Use some common sense here: If I say Band-aid, do you know what I am talking about? If you say that's only a tradename, and you refer to them as adhesive bandage strips, I am going to guess you were toilet trained you with a cattle prod...
