RSS support used to be built into the browser, with identifiable iconography.
You'd click a link on a website that says some iteration of "subscribe" or "feed" and the browser would handle it for you, putting the feed into your bookmarks or whatever.
Users never had to know what RSS is. They just clicked "subscribe" and it worked.
You'd have to do the same explaining of Bluetooth or WiFi, both things that non-technical people are familiar with today, if OSes, for some reason, removed support for them.
