Most of the major news websites still offer RSS feeds, although you do have to search quite a bit to find them. NYTimes, WSJ, Vox Media, The Atlantic, Time Magazine, etc etc all have them. Those last two are even full-text feeds, which is super lovely!

I have a suspicion that journalists rely on RSS more than the general population, which gives the technology support within news organizations themselves.

I can speak first hand to that, in Canada. RSS is actively supported. Specific RSS feeds are even run to (web, Apple News) aggregators after agreements are made to syndicate the content.

And we maintain feeds for the Canadian government archives.

I can only imagine American outlets do something similar.
