Agree with last sentenceYou're both pointing out the risks that multi-national companies with lots of competition are taking when they speak out politically. But it's a business risk, and I'm absolutely certain it's calculated.
Now, if a company like Coke were to receive legislative favoritism in exchange for political activism that would be problematic and perhaps dangerous. But personally I wouldn't care much more if Coke was contributing to preserve Stone Mountain. It's their choice, and I have lots of alternatives if I don't care to buy their product.
