Nah, CFCs have been shown to degrade ozone in the lab, and they are banned pretty much world wide, including China surprisingly. However, the ban was not really needed as the primary release was due their use as refrigerants, and we were able to find better gasses for those, which significantly reduced demand of CFCs in general. The hole is still around BTW, but it's gotten much smaller, and you don't hear much about except in places like Australia, which is still affected by it.
