CFC ban was a huge scam. Patents were running out on old refrigerants so manufacturers created new ones with new patents in order to maintain their huge profit margins.
...AND, NASA wanted a budget increase...that would include “studying” the “CFC-created” ozone hole...
ABSOLUTELY. The automotive industry was the worst of fraud. They actually spread the lie that older systems could not also use the newer freon. Absolute outright criminal fraud, they do just fine loaded with 134. Billions of dollars were made because folks bought new cars they didn’t need or retrofitted older systems they didn’t need to retrofit because of this scam.
