US developers can offer non-app store purchasing, Apple still collect commission

This is a huge win for the developers, despite that pesky warning. They can still ask users to circumvent apple pay/in-app purchases and get away by not giving a revenue cut to Apple.

They might just get away with something as crass in a vacuum, but given that the DMA will go into effect very soon, there will be a point of reference in a similar economy, and I don't think it'll be pretty for Apple.

US regulators (federal or state; I could see something equivalent to GDPR and CCPA) will be taking a very close look.

They are taking 27%, between that and processing fees you might as well use In App Purchases.

"Apple’s commission will be 27% on proceeds you earn from sales (“transactions“) to the user for digital goods or services on your website after a link out (i.e., they tap “Continue” on the system disclosure sheet), provided that the sale was initiated within seven days and the digital goods or services can be used in an app. This includes (a) any applicable taxes and (b) any adjustments for refunds, reversals and chargebacks. For auto-renewing subscriptions, (i) a sale initiated, including with a free trial or offer, within seven days after a link out is a transaction; and (ii) each subsequent auto-renewal after the subscription is initiated is also a transaction.] If you’re a participant in the Small Business Program, or if the transaction is an auto-renewal in the second year or later of an auto-renewing subscription, the commission will be 12%. These commission rates apply to all amounts paid by each user net of transaction taxes charged by you. You will be responsible for the collection and remittance of any applicable taxes for sales processed by a third-party payment provider. If you adopt this entitlement, you will be required to provide transaction reports within 15 calendar days following the end of each calendar month. Even if there were no transactions, you’re required to provide a report stating that is the case. If the cadence changes, we will update this page. To learn about the details that will need to be included in the report, view example reports. In the future, if Apple develops an API to facilitate reporting, you will be required to adopt such API within 30 days with an update of your app and follow the timing and requirements provided."
