Not just network operators versus platform owners
As the article author states. If it was just those two, they could probably come to some agreement.
But the payment processors want to make sure they get their cut, and that it is at least as large (if not larger) than they get from credit/debit transactions today. This is why they want to link NFC to individual credit/debit cards, rather than phones, and are pushing retailers to install NFC capable readers - not because they care if anyone actually uses NFC, they just want to stop Square or Paypal from installing NFC readers that would cut them out.
The network operators think that since they're already billing people monthly, they should add all the transactions to that monthly bill and cut the payment processors out. This is why they want to link NFC to the SIM.
The platform owners, Apple and Google, already have banking/credit card information for many millions of people via their app stores, and would be happy to take that cut instead of the payment processors as well. Not to be left out, the Android OEMs, especially big ones like Samsung, no doubt believe that they deserve this revenue instead of Google. This is why these guys want to install NFC in the device, not the SIM.
The payment processors and their overlords, Visa and Mastercard, can also play the merchants and consumers off each other. The merchants want to pay lower processing fees, and consumers want the freebies that go with their credit (cash back/miles) and debit (higher interest rates, no fee accounts) cards. Can't have both, so while merchants may try to push NFC if they can get lower fees, they'll have to offer something to consumers to make up for losing their freebies.
There are just way too many corporations and interests fighting each other who each want all or most of the revenue pie. It is made even worse that one of the players owns this market and will lose their current revenue stream if NFC is adopted in a way that's outside their control. They'll do anything and everything to make sure that doesn't happen. NFC has no chance against all this, even if the very real security issues of a "near field" protocol that can be easily read from 10+ feet away with less than $100 of equipment didn't exist.
