I never stopped using RSS even when it supposedly "died". Right now I have FreshRSS running on my raspberry pi since I like subscriptions and read state to sync between my machines but don't like to depend on some company for that. I use Reeder for my iOS devices, which can sync with FreshRSS.
For all folks say RSS is dead, I find a lot to fill it with. Blogs (yes I still read blogs like it's 2005), webcomics (most comics with their own site offer one, and webtoon generates them for its comics, though it looks like tapas doesn't or at least I can't find any feeds there), tech news sites, scientific journals, lemmy and mastodon generate feeds for users and communities, even YouTube still generates feeds for individual channels. There's a lot of feeds still active out there.
RSS is definitively not dead. I threw $99 for a lifetime Feedly subscription about 15 years ago, rather than roll my own aggregation, and it's been my primary news source since.
