Right MCD is just looking over at KO and going us too.
A few loud people online and embittered animators are complaining about their ads. That handful of people might be mad about it. Meanwhile in terms of numbers that matter everyone else going out of their way to watch the ads, like seeking them out, just to see what all the fuss is. So they get tons of free ad impressions, and if they are lucky a few of those people say "gee haven't had a Coke in while, sounds pretty good, maybe I'll buy a case."
I haven't met anyone in IRL who is actually mad at Coca-Cola for their AI ads, but they are talking about them. Even if the sentement might be 'the old ads had more soul' it isn't changing their opinion of the product or the company really, and it is bringing it to top of mind. - Just what the ad men want..
Hard to image every other corporate marketing department isn't trying to figureout how to get in on that without appearing a little to 'us too', the funny part is that last part really does not matter either probably, they only worry it does.
