Does this belong in r/technicallythetruth

My teacher told me about this in school so basically at a certain point Pepsi was more popular than Coke so Coca-Cola made a new Coke that tasted like Pepsi but the problem was the people who drank their product weren’t drinking it because they like Pepsi they were drinking it because they like Coca-Cola so they ended up just losing their customers so they had to make another new one calling it Coca-Cola classic
