What I seem to recall is that when Coke was withdrawn and then reintroduced as "Classic," following the "New Coke" circus, corn sweetener (or something) had been substituted for sugar cane in the transition from Coke to Classic. I don't think that change would have been at all well received had the company simply changed the sweetener in Coke; but it was completely distracted from by the ruckus. "Classic," in fact, got applause when "it" was brought back. Made me wonder if that were intentional. Someone will correct me if I'm wrong. I don't drink soft drinks.
