Apple Pay has no traction.
You'll feel better as a result of sending your missive, but it'll be too little too late. Target, Rite Aide, Walgreens, CVS, Sears, Walmart, Best Buy, Kmart, 7 Eleven and others have swiftly reacted to the Apple Pay situation, it's problems, complications, and walked away. The last thing these retailers need is to be unwittingly drug into a payment system abyss.
If it should be proven that there's some merit, some advantage to Apple Pay, I would think they might revisit it in another few years. Apple has staying power, there's no rush to implement Apple Pay. By taking time to review what went wrong and how it might me fixed, will be a very good lesson for Apple.
Look how easily Apple ignored it's loyal customers for two years, preventing them from having the 5.5" display they wanted so badly. The temporary failure of Apple Pay won't affect Apple.
This is Apples game, in Apples ball park. They'll continue to do what they want, when they want, and customers will praise them for it. All is well
