So instead of 1% of all mobile purchases going to Apple, it goes to walmart instead. With the scale of business Walmart had that can be upwards of a billion dollars a year.
Argh. I had the same thing happen. Just after getting used to using the tap-to-pay card, my bank replaced it with a "dumb" card and I was back to swiping it.
Having it as part of your cell phone makes it much more secure (Apple Pay requires your fingerprint for it to work).
Contactless cards can get skimmed:

By the time you defeat TouchID, the device will be useless anyway. It's more than secure enough.

I've used this regularly for the past few months and had no real issues with it.
Double-tap watch or iPhone button, wave device near register, done. Fast.
That vs Walmart Pay tap iPhone button, [swipe to find icon,] tap icon, wait for app, tap scan button, position camera for QR code, wait for focus & recognize, done. Too long.
I tried Walmart's Scan-and-Go app. Idea was you could scan all your stuff before reaching the register, scan one QR code, pay, and leave. Took an inordinately long time. Walmart dumped it.
Edit: actually there has been a "tap to pay" available at many places. All too often it was turned off, and mildly confusing which cards had it (I had one that did, then its replacement card didn't, so there I was waving a non-tap card at a tap reader). The whole tech fizzled.
