I thought that too, but oakmoss is still used in the EU (e.g. C&S No.88 edc/edp).
Although it has been blacklisted in the EU, it is still possible to use up to 0.1% in fragrances. However, for an ingredient that has been fundamental in many famous fragrances, this limitation changes the scent of the fragrance.
Chemists/perfumers have learned how to distill oakmoss to remove the offending ingredient that causes the rashes in sensitive individuals. Thus, it may be that the fragrance you reference may be using the "refined" oakmoss. Apparently, celery seed is added to make the refined oakmoss smell more like the original. My point is that this was a modification driven by governmental regulation rather than by customers.
Customers who are sensitive to oakmoss could simply choose not to use products containing that scent, just like I choose not to purchase products with a high concentration of lime, lemon, grapefruit, mint, clove, and cinnamon. I do not go to the government and demand that products with these scents be removed from sale because I have an issue with them. It would be one thing if many people had life-threatening allergies to the ingredient, but a skin rash is not life-threatening.
