Interesting analogy, but why wannabe-colas?
Not everybody loves Cola, coca or pepsi. It's a drink derived from the U.S, which is really implemented into world market (McDonald's has made it very popular), but there are many other drinks which some consumers prefer: juices, beer, national drinks.
Coca-Cola is the ruler, but when you want to drink you can choose.
And now imagine that you have nothing but Coca-Cola or Pepsi. Would you like it?
