Not sure what it's like in the US (or the EU), but in Canada, all banks effectively offer the same level of customer-hostile service.

Without a doubt, they'd roll their own fragmented/compromised implementation of contactless payments on iOS, if they had the choice.

Not quite the same, but so many large corps in Canada don't offer Wallet integration for their relevant products (loyalty cards, points balances, etc.) They instead have their own app for these, and let me tell you: they are all garbage.
