You are correct. The original environmental myth was that refrigerants containing chlorine and fluorine were destroying the Earths ozone layer. Looking at this with a little common sense, you can see that it all was based on fraud. These refrigerants are heavier than air and break down at around 1200 degrees F. How do they get into the upper atmosphere? How will they break down in the environment?
The dirty little secret behind this is that DuPont “admitted” that refrigerants “may” be an environmental hazard. This just happened to occur about the time that their royalties on these refrigerants was expiring. DuPont made billions of dollars worldwide on Freon royalties. BTW, Freon is a DuPont trademark.
DuPont came in and saved the Earth from environmental disaster by developing a whole new family of refrigerants to replace R-11, R-12 and R-22. Rest assured that they will continue to collect billions in revenue for many years to come.

One of my favorite SNL skits was Aykroyd and Morris being “scientists” at the south pole studying the ozone hole and they all had big hair and were vain on themselves continually spraying hair spray to fancy themselves, all along reporting back to the US that the hole in the ozone was growing at an alarming, uncontrollable rate!!

Convincing the American public to believe freon was the culprit for ozone depletion sounds like it was the catalyst for the AGW scam.

"These refrigerants are heavier than air and break down at around 1200 degrees F. How do they get into the upper atmosphere? How will they break down in the environment?"

Sorry, but this isn't true (or more accurately, isn't the whole story).

Yes, the Freons are somewhat heavier, but the driving force from concentration differences will still drive "some" molecules into the stratosphere. And there are other driving forces at work. Thunderstorms are also particularly effective in forcing vertical circulation, even of heavy molecules (Freons are not very soluble in water drops).

And yes, the Freons ARE very thermally stable. But the breakdown mechanism in the stratosphere is photochemical, not thermal. UV radiation is present in the stratosphere which doesn't reach ground level, as it is blocked by the oxygen in the atmosphere.
