RSS is great. Most blog engines support RSS by default. Podcasts typically use RSS (even if the app goes to great length to hide it). I sometimes wonder why there is so much push for "federation" and so few for... well just simple interoperable solutions that just require a client to connect to whatever server it wants with a well-known protocol.
Where I have RSS feeds from news sites, I usually skim down the list of titles, read an article (in my feed) if it's interesting, and then move on. I never visit their website, I don't see their adverts, their tracking scripts can't run, and I don't see or interact with their comments. Which is great for me as the end user - but makes it much harder for them to monetise.
On the other hand, RSS definitely provides extra opportunities to monitise. Imagine your business provides a customisable "offers" feed so you can tell interested parties when a sale occurs, etc. Businesses should be falling over themselves to get that kind of engagement.
