When you start following pages of news outlets on Facebook, your feed starts to be filled with news coming from them, making it seem somehow like a RSS reader. At the beginning it even used to somehow work, but in the last few years the content selection algorithms started to be so heavily optimized towards user engagement - likes, comments, reactions, shares - instead of providing interesting content that it became clearly visible, and the difference between a reach of promoted posts and regular one increased massively as well, in turn making Facebook's feed useless as a news provider.
