Those chemicals are not gone and I believe their production has not stopped in all countries. Their production is certainly curtailed but these long lived compounds are still present. I was schocked to hear the ozone hole was shrinking just a few years ago because it was my understanding recovery would take decades. Freon is still used in a lot of old refridgeration equipment, but is now carefully recycled to prolong the life of this equipment until it fails mechanically.
For a more balanced view than Tom's typical anti-environment stance:
Arctic Ozone May Face Long Term Threat
Destruction Of Ozone Layer Slowing As CFC Ban Begins To Work
Unusually small Antarctic ozone hole this year
Wide annual fluctuations found in Arctic ozone loss
Check out the source link. You'd never guess space news sites would be environmentally conscious given the general attitude of the generally pro-space crowd here.
As with the greenhouse effect anti-environmentalists use short term variation as an excuse to ignore long term effects or implications.
