This is a good argument, but I'm not sure that I buy this. There are plenty of industries (I think of the cable and cell-phone industries, but I'm sure there are others) where it's just a given that the service will be crappy, even though one company that started to respect its customers could seemingly corner the market. (I'm not sure what are the results of T-Mobile's exercises in respecting its customers. Their unfortunate net-neutrality stance with Binge On means that it's not an unalloyed win to go with them.)

I get what you're saying, but credit cards are unique: the advantage credit card companies have over those other industries is that there is essentially no lock-in, and your old cards continue to work while you're in the process of switching eg your autopays over. It's a very switch-friendly industry.

Remember when you couldn't take your cell phone number with you and so pretty much nobody switched carriers? It was a massive pain. Now it's easier than ever to switch, except most people are locked into multi-year contracts. Switching friction = high, but not impossible. As you said, TMO is trying to compete here.

Cable has monopolies on towns, so there's 0 incentive. People couldn't switch even if they wanted to. I suppose there's satellite, but you'll still be paying the cable company for internet -- they get their pound of flesh no matter what. Switching friction = impossible.

These are good points. My remark was off the cuff; it's clear that you've thought (or at least are thinking) about it much more deeply.
