I think this differs wildly between countries. I know that Discover/American Express wouldn't have close to 30% of the market share in Europe, it's only some shops that do accept those, although it's becoming more popular. In the countries I've been to in South America, things have been more or less similar.
Also, I think that link of yours (although I cannot read it fully) is about the percentage of transactions, rather than number of merchants that accept it. So it's basically more about the card holders than the merchants accepting one vs the other.
