I'm not seeing any predictions here that there is a problem with the ozone layer. The citation for the wiki quote you include seems to be saying that they still expect improvements in the ozone layer vs the present because we have made changes that should lead to the ozone hole repairing itself. This is also the overall conclusion that the Wiki article appears to support too. The sulfide modelling paper is saying they have expect problems at sulfer emissions far greater than currently anticipated.

I'd say that the reason nobody is doing anything is there does not seem to be a threat being detected. There are scarier problems to work through (mainly war and access to energy).

> is expected to produce an increase in ozone depletion … and the frequency of ozone holes

Sounds bad to me. Not the worst to come out of climate change, but potentially very negative if it comes to happen. More ozone holes and more ozone depletion can’t really be spun positively.
