Let me do the same - The user went through multiple screens that told them exactly what would happen and when. That isn’t misleading so it cannot by definition be duplicitous. Do I think there is room for a more user centric design? Yes. Do I stay away from subscription based iOS apps? Yes. Do other people use them and enjoy them? also yes.

It is - free trial with automatic rollover is set up anticipating that people will forget to cancel. It is not being offered as a good faith service.

Inherently if you are relying on something to thwart or subvert the intention of the person you are dealing with you are engaging in duplicitous behavior.

I’ll ruminate on the good faith service argument. That sounds like a valid angle. I see many of these app subs are predatory and wished apple provided a way to filter them out of search results. But I don’t consider the offering of the subscription functionality to be wrong. Apples implementation errors on the side of their pocketbook by being an auto enroll, but the signup screen is easy to read. It’s not buried in some TOS. Everyone who enters the agreement did so willingly and presented the terms cleanly. I understand they have a 14day return policy on these as well. At some point, people have to be responsible for their own financial decisions.

Yeah, I find it convincing. The principle I'm operating under is that both parties should benefit from any given agreement and that intentional efforts to subvert that are automatic non-starters.

I won't make the argument that subscriptions or even auto enroll are necessarily evil if we're shifting focus to less predatory industries, I would judge a given example by how difficult it was to get a refund. I think the top level principle of mirroring ease of subscription to ease of ending such applies here too, with respect to ease of billing for an unused service.
