From my limited understanding of how Apple News works, there's two formats to get information published in Apple News: (1) RSS feeds, and (2) Apple News Format. In order to be featured in Apple News, a publisher must (1) first sign up, and then (2a) submit RSS feeds or (2b) wait for and use the Apple News Format to create rich content.
It sounds like there might be some misinformation about how this works being spread by confused publishers? Can someone point me to a claim that Apple will be crawling a publisher's website and ingesting their RSS feed(s) without their express permission?
By publishing an RSS feed permission is implicitly given. There is no such thing as stealing someone's RSS feed.
