> that’s why some content authors, like Daring Fireball’s John Gruber, as an example, only provide their full RSS feed to paying subscribers

This is false. I am not a paying subscriber, but I still get the full content of Daring Fireball articles in my RSS reader. In fact, the RSS feed is one of the links on the site’s sidebar. https://daringfireball.net/feeds/

That's not the "full feed", that's $19/yr and mentioned here: https://daringfireball.net/members/info

> However, paying supporters do get access to a few members-only perquisites, including separate full-content RSS feeds for articles and the Linked List (my daily list of links and blurbs related to Mac, web, and design nerdery).
