Yes, freons are still used today as refrigerants. No one knows if any freons actually damage the ozone layer. The argument has raged for years. R-12, the freon that was banned is actually heavier than R-22, a freon which was not banned, and is still in use. It is also heavier than R-134a, which I believe is now the most common freon used.

#1, regardless of what has been said, there has never been any real proof that R-12 was any where near being the cause of the ozone issue. Think about it, the patent on it was about to run out. Rather than let it be produced by just anyone with the means, and thus under cut the company making it, WOW look at this, it is the cause or at least part of the cause of Ozone depletion. Answer, get rid of it, thus the producer cuts off competiton. Yes, while they will never admit to that, it is most likely the very cause of the demise of R-12. As far as refrigerants go, yes, they are still being made. R-22 which is used in large air conditioners is one of them. I wonder what the reason for it's cancellation as a refrigerant will be? It isn't that far away either. No, refrigerants and their alledged Ozone problems are still with us.

R-12 (Classic Freon) is no longer being made in the US
It is being made in some other countries.
Most newer refrigerators and window AC units now use R-134a Sometimes this gets refered to as freon, but that is a "misnomer" (like calling Puffs brand tissues "Kleenex")
R-22 which is less damaging to the environment is still used in larger AC systems.
There are a few other refrigerants used in larger industrial cooling systems.
