I'm not sure what your Wikipedia quote is there for, all it says is that (news flash!) CFCs are man made. So is steel, maybe that's the issue.
The Ozone Scare was a great example of acting before the facts were in. They discovered the hole in the mid 80's, and they found it was getting bigger. They knew that CFCs destroyed ozone, they could replicate that in the lab. They kind of neglected to explain why the hole was over the south pole when most of the population is in the north, I guess CFCs are heavy and sink to the bottom of the planet. Or maybe Aussies smell bad and need a lot of deodorant. It was the 80s so we won't talk about the hairspray... Some people pressured the government to do something about CFCs (won't somebody PLEASE think of the children!) and, luckily, replacement compounds were available so the government banned them and industry switched to "green" compounds and we now all pay a little extra for deodorant and hair spray. But the earth was saved!
But the ozone hole is still there. And it's growing. And also shrinking. Turns out that we now think the ozone hole may have ALWAYS been there, at least since before the industrial revolution when most people agree pollution really started. It also has cycles, both seasonal as well as cycles that last longer periods. Banning CFCs had a negligible impact on the ozone layer and was generally a waste of money and effort, but people feel good about that CFC-free sticker so there's no need to say "mea culpa" and apologize. The lesson to learn here is that the knee-jerk reaction to doomsday media reports is often pre-mature and, more importantly, the media are awful at retracting these stories. In fairness, the general population is awful at watching those stories.
Now, ironically, too much ozone in the lower atmosphere where the CFCs were used is bad for you. I wonder if bringing back CFCs would help those with breathing issues on those ozone-filled summer days?
If you had cited sulfur compounds and acid rain or anti-smog devices those could be seen as wins for the environmentalists. Unfortunately I'm with the founder and ex-head of Greenpeace, he quit the organization because they started to focus less on the environment and more on politics and punishing evil corporations. That's why CO2 is the big baddie now, it covers all internal combustion engines and the majority of power generation (oops! forgot and those evil nukes). They never mention water vapor, which is much more potent but would kill the hydrogen fuel market. Nor do they mention methane, because the best way to prevent methane is to prevent trees from decomposing. Either burn them or turn them into lumber before they get the chance. Climate science today is like medicine during the civil war. We know enough to be dangerous but there's a long road ahead before climate models can even come close to predicting what's going on. So we'll take a look at the cost of each bugbear they come up with and decide how serious the threat is and how expensive it is to fix. With CFCs we got off easy, no such luck with CO2.
