I hope your not being serious, but don't see any sarcasm tags.
In the event you are, or people seem to believe you, the fact that these locations have had NFC terminals for quite some time and they have been working all along goes to show how much traction ApplePay has. ApplePay uses the same basic infrastructure as Google Wallet, PayPass, PayWave, etc... which have been working for years. All of a sudden people are using their iPhones to make purchases and now its a problem. This shows that MCX is afraid that this ApplePay thing might actually catch on, validating the whole NFC payment thing in the US. ApplePay uses a version of EMV and if that catches on and more implementations spring up (which is possible since its all the same back end) then it makes CurrentC less attractive (not that it is at all anyway).
If ApplePay had no traction then they would have just left the systems on and accepting payments. You can argue that GoogleWallet, PayPass and PayWave had no traction since they didn't care when people were using those. Now that people are using ApplePay, its a problem. I'd say thats pretty good traction.
I don't see how anyone can at all argue in favor of MCX on this one. Regardless of your views on either system, both systems should be allowed to run their course. Thats how competition works, right? Run NFC along side CurrentC and let the public decide which one they prefer. If your going to accept credit cards anyway (via magstripe swipe) then your already paying the transaction fees and ApplePay doesn't cost anything extra. MCX see's the writing on the walls that their system is going to fall on its face and are having a panic reaction.
All disabling NFC systems going to do is cause payment system fragmentation and that is simply lose-lose for everyone.
