I was a teenager in the 80s, and I was aware of the hole in the ozone layer, and that CFC caused it. I didn't read scientific rags back then.

I did.
And that hole was already closing by the time you heard about it. They were theorizing that it was a natural phenomenon. They know a little better now but it still seems to close every decade or so.

Ok I’ll bite. What is your outlook on man made climate change.

irrelevant to this conversation.
im not denying the hole exists. im only pointing out that it seems to be closing every couple decades. in fact, it was closing shortly after they discovered it.

Which ones?

While I didn't read scientific publications in the 1980s, I did watch the news, and the signing of the Vienna Convention for the Protection of the Ozone Layer would have made the news.

The hole is constantly opening and closing, as there are natural seasonal variations. It appears that it is a natural phenomenon that is made worse by human pollution. While the fight against ozone-depleting substances have largely been a success, there have been setbacks:

That's exactly the point.
Too bad the article and none of the other media say that. All the media ever does is post a "yay we fixed it" pat on the back article about some legislation that was passed, like banning CFCs.
