To be fair its not a very good metaphor I was just pointing out that the initial point was fairly arguable, and honestly Coca-Cola was just an example I pulled out of thin air, and not a very good one being that it is a fairly easily manufactured food product, easy to replicate and such. But as long as we are on it, notice that Thumbs Up Cola was introduced
after Coca-Cola left India and was therefore no longer a competitor. If Coca-Cola had not left India, their monopoly on delicious coca-flavored beverages (damn now I want a coke) would likely have continued and Thumbs Up would not be in existence.
I would also like to point out that I've spent a fair amount of time in India, and you do mostly see Coca-Cola products. You do occasionally see Thumbs Up (sometimes restaurants will have both), but I never saw Campa Cola. If you look at the wikipedia page for that brand, you may notice that it was India's most popular coca-drink until Coke was re-introduced to the market in the early 90's, after which time they simply took over the market share.
But again, I don't even really think relating what American companies (and therefore America, I don't care what anyone says, thats our government's fault for not having more regulations) do in 3rd world countries to "monopolies" is even the right connection to make. Just pointing out that its arguable.
