The way those franchises work is that they need to pay a fixed percentage to the US parent company as license fees for the use of the brand. So no matter how much of it is locally produced, bottled, consumed, etc., part of everything goes to fund the US government (through taxes on the profit of the US company). A total boycott of whichever regional outlets you have is the only way to cut the money flow.
The brand might not be European but they have been producing and bottling in Europe since forever. (Excluding producing some ingredients of course)
