RSS isn't as ubiquitous as it used to be, but it's still very common. It's pretty much the only way that I keep up with websites I care about, and there are very few of those that don't offer an RSS feed.
They don't always advertise the feed, though, and since browsers stopped being RSS-aware, I've taken to looking at the page source for a new site to find if there's an RSS feed mentioned in the metadata. Very often there is.
(1) Paywalls and content monetization
You absolutely can provide RSS feeds that require a login, so paywalls and such are a supported use case.
To answer your direct question, I do provide RSS feeds for my sites, but all of my sites now require a login.

Often RSS feeds are not even in the page's metadata. There are tools that can help find them, basically by trying out common suffixes for feeds.
One such tool is https://lighthouseapp.io/tools/feed-finder
