Totally agree that it's best for responsible people. But what is Apple's goal here — to increase the number of people/merchants using Apple Pay or hitting people with unexpected interest payments, which would sour them on the Apple brand? I would think that they're trying to grow their ecosystem, rather than make money while alienating customers. I could be wrong though — when times are tough, even good companies do lousy things.
I don't really think Apple's interest is in collecting interest on these payments, but I do think it will cause people to use Apple Pay more because it enables (perhaps encourages) them to buy things they otherwise wouldn't buy. That can be good or bad depending on the circumstances, I just expect this will be frequently utilized in an "impulse buy" sort of way because it creates an illusion of affordability.
