It's not likely as sinister as you make it out to be, I could not find out what "A2 regulation in June 2020" means, but I suspect they are phasing out older refrigerants, but allowing sale of existing stock. For example cars need to switch from r134A as of 2022, but before that it's fine, and home A/C's need to switch from R410a as of the end of this year, but they can sell existing stock for another year. So prioritizing for sale makes perfect sense, and doesn't indicate anything nefarious, just selling out of old stock, exactly as the law is suggesting. Edit: I'm virtually certain this is R-134a being phased out in Australia in June of 2020. And I figured out A1 and A2 which are flammability ratings of refrigerants. With R-134a being A1, and the new ones being slightly more flammable and are rated as A2.
