CFC's have been switched over in large users like compressors and air conditioning equipment. Meterd dose inhalers are the last to go just because people want time to try other techniques.
For once I can sympathize with ceej, since CFC's are such a minor CFC source, why not just let them stay on the market. Hell, car air conditioners were the worst source by far. I dont know what the percentage use was , but Ill bet AC units accounted for >95% of the CFC product.
Im not sure that HFA's are any better. The molecule is a bit lighter and its semi conservative so itll still retain its unit character in the atmosphere. Why not switch all AC units back to Ammonia
