Pretty much the only threat to the Visa/Mastercard duopoly is public awareness that leads to antitrust enforcement. They're usually immune to any kind of backlash but this seemed to strike a cord with many people who are frustrated with America's puritanism (myself included). I don't have a dog in this fight but it certainly reminded me how much power V+MC have to become an existential threat along the likes of Google and Spectrum. Next time I write to my Congressman about antitrust, I'll be sure to put them top of the list now (for all that's going to do...)
