This hurts. RSS is the only way I know, without having to scrap things by hand, to get an aggregate of "news/articles" from the sites and blogs I follow, and I consider to be of good quality. I prefer to filter my information like this, instead of having to rely on some algorithm, or endlessly scrolling in a "social medial wall" full or clickbait articles, immortal/vintage memes or exuberant rants. If RSS dies, what…
Well, that's the whole point - RSS lets you circumvent all (or most of) the mechanisms that Facebook, Google, Medium etc. etc. have implemented to monetize content. So they are directly interested in killing it off sooner rather than later. And if the big players don't support it, the people/organizations/whatever who still maintain their own blog/news site are also more likely to see it as obsolete (or have web devs who tend to follow the "new shiny" and will advise them that RSS is obsolete).
