It has everything to do with parents. Sure, they tell a nice story about saving the ozone (that was already closing) but it's convenient that every time the parents run out, it gets banned and there is a shiney new refrigerant that is "so much safer".
Whether it really is safer or not, they come up with a new one everytime patents run out.
R12 ran out in the 90s. R134 ran out in the 10s. The new one will run out in the 30s.

Ozone hole was closing due to banning of CFC. CFC was extremely harmful to the environment.

R-22 is less harmful but still has an ODP, and a stronger GWP than r134a.

Not everything is a corprotacracy conspiracy.

Nobody is disputing that.
Just pointing out that it's very convenient for the parents. If you think corporate America gives a shit about anything but their pocketbook then you need a serious reality check.
Also, the ozone hole was closing before the cfc ban.
