If it's truly accidental (as in a rogue employee or a script that f'd up), they probably have a legal basis to break the contract/license terms and retract it. Just as stores are not required to honor misprinted price tags. There will likely be a court case if someone believes they legitimately received a GPL-licensed version of the code and wants to use that code in another project (or pass it on to others). Like I said, I think Adobe has a good case to win that here.
If it's "accidental", and they're just trying to walk it back, there would definitely be a court case. Whether they'd win or lose would be very up in the air, and probably depend on the jurisdiction's friendliness to businesses.
