I don't think many sites
removed RSS, but many new sites and services in the last ~5 years, never implemented or served it in the first place. The typical share icons now are FB, Instagram, and Twitter. Email is less common (although usually there's an email newsletter signup). For a while, there wouldn't be link to RSS on the page, but you could still find the .rss or .atom link in the HTML header. But a lot of times that's not there anymore either.
It makes me sad to have to settle for Liking a company's FB page, since it's up to FB whether or not I ever see it.
