It's not a 1:1 replacement -- Forth is a news feed for news, more like a social feed, but all the posts come from verified journalists. We're still bringing on news orgs/reporters, hitting local to world, and various niches in between.
Nextcloud running the News app [1] on your own server, either an old laptop/desktop or a SBC like a Raspberry/Orange/Banana/${fruit} Pi. You'll get total control over whatever you do with the thing, as much 'free' cloud storage as you want and loads of other possible services. It runs fine on a Raspberry Pi 4 or one of the equivalent boards from other manufacturers.
Source: I've been running this before the Owncloud/Nextcloud split, it works as advertised.
Right before Artifact released, i was working on a similar NewsApp and I released LetMeKnow.news on Google Play and App Store some months ago. I use AI to summarize news articles, users are able to comment articles, create polls and vote, like/share. I would love if folks can check it out and provide feedback.
It's a new app, please be easy on me :). I am working hard to make it a great app, would appreciate your feedback! I am currently working on clustering/grouping similar articles, this feature will be released in 2-3 weeks.
Google Play and App Store links are at the bottom of the landing page: LetMeKnow.News
Have you considered an area where additional news sources can be suggested, or perhaps allowing subscribers to introduce additional news sites? This is a great site, and I use it regularly, but because it is curated by you I lose some control and ease of access. As an example, you include sites like the Intercept and Fox News, I suspect to introduce balance, but do not for example include Al Jazeera. This leads to your site aggregating with the inherent bias from your sources.
I loved that Artifact offered Dark Mode on it's articles.
