I don't get it -- Amex and Discover are still providing healthy competition, so the "duopoly" the author complains about seems to be largely irrelevant. Competition between cards is thriving and consumers benefit -- witness the miniscule transaction fee the credit card companies keep after paying your rewards back of 2% to 5%, when you pay your bill on time.
The article's main point is that such large companies are a cybersecurity risk, and that the government should regulate/nationalize/globalize payment infrastructure.
Unfortunately, experience tends to show that governments would be far worse at providing secure, low-cost payment services. Also, credit cards already are highly regulated when it comes to consumer protections.
So, this article is just not making a lot of sense to me.
