@DozingCat And I just saw that I was partially mistaken about the source of controversy being the removal of alcohol, as back then it was still meant to be a substitute prescription medicine to Morphine (caffeine was produced from Kola nuts), those legislations what caused Coca-Cola to exist (the original recipe was called "Pemberton's French Wine Cola") as a nonalcoholic version of it for general consumption.
People were annoyed when sugar (I presume cane sugar) was replaced with corn syrup.
