Did they know they were going to piss off American conservatives? And if so, did they care? If there is a global market for anything, it is for Coca-Cola. Chances are, the multinational was willing to sacrifice a tiny fraction of 1% of market share in the US (if even that) to gain more customers globally.
But for many conservatives, the issue goes well beyond market-share. How dare Coca-Cola allow "America the Beautiful" to be sung in foreign languages? If Jesus had wanted that, he would not have written the song in English in the first place.
