I'm unclear on the implications of Apple's App Review Guideline 5.2.2: If your app uses, accesses, monetizes access to, or displays content from a third-party service, ensure that you are specifically permitted to do so under the service’s terms of use. Authorization must be provided upon request. If a paid subscription app uses a licensed search API to retrieve and display links to publicly available third-party web content, is the API license generally enough for compliance? Or does Apple expect separate authorization from each underlying website whose content appears in the search results?
