These might be the three most meaningful paragraphs of policy/legal mumbo jumbo I've experienced in my professional career.

From an inconspicuously titled "Updated guidelines now available" from @developer.apple.com:

3.1.1(a): On the United States storefront, there is no prohibition on an app including buttons, external links, or other calls to action, and no entitlement is required to do so.

3.1.3: The prohibition on encouraging users to use a purchasing method other than in-app purchase does not apply on the United States storefront.

3.1.3(a): The External Link Account entitlement is not required for apps on the United States storefront to include buttons, external links, or other calls to action.

The email opened with an acknowledgement of this week's monumental legal mandate:

The App Review Guidelines have been updated for compliance with a United States court decision regarding buttons, external links, and other calls to action in apps. These changes affect apps distributed on the United States storefront of the App Store

Three cheers for regulation?! 👩‍⚖️

The most exciting thing about this to me personally is how @apple.com itself might respond to these changes by actually competing for developers' business in an area where it hasn't had to in the past.

It's gonna be a fun #WWDC & summer! 🙌🏽
