The problem RSS solves is it prevents your whole world being captured by a particular community, instance, server, platform, company, whatever. Half the Internet is having an existential crisis over the Reddit implosion. RSS users aren't - we're kind of shrugging our shoulders and saying, well that's one of 10 places we get community, info, whatever, sure it's a big one but if it vanished overnight (which it sort of did) 85% of my feed would still be there.
Reddit, Lemmies, blogs, podcasts, Mastodon instances, weird alt Tube sites, the Chans, the Tildes, SDF, probably more - contrary to recent HN posts about how all the web feels "samey" now, it's a big 'net out there these days. It's merely a question of the company you keep. If you only ate at chain restaurants, you'd feel that food has gotten pretty lame too.
