BS. The CFCs that last 40-50 years average in the atmosphere are inert and do not nibble at anything. When they reach the upper stratosphere, after their possible decades of inert life, a percentage is broken down by ultraviolet. The free chlorine can then nibble at ozone for a 2-3 years until it falls back down to earth. It's absolutely no different from natural chlorine from volcanic eruptions. The worst case for eruptions is about a decade.
Granted there is an added chlorine load due to CFCs. But the longer the lifetime for the CFCs, the smaller added chlorine load is. Also the lack of ozone loss this year just like 2002, shows that weather is a big controlling factor.
It seems like the patents for R12 had run out anyone could have produced them.
