It's more than just one-time IAP, though. I'm generally "whatever" on what payment processor people use, but one of the things that does concern me is subscription management. To me there is a lot of value to having a central place where all my subscriptions are and where they can be canceled easily, even if I don't have the app installed anymore. YOLOing something with Stripe doesn't give me that without a bunch of fundamentally opt-in stuff on the part of the developer, and that's pretty concerning. If the platforms can (and do) solve this, then I feel a lot better about it.
