This is exactly what I was looking for a couple of months ago. I’d even posted an Ask HN  on it. Please reply to this comment if you know of similar setups where one can use an aggregator and get the feeds in a local reader as if the subscription was done in the local reader app (I don’t like web interfaces for feeds since it may not work offline and may not download and cache all the feed data for offline use).
I’m still using a commercial reader/aggregator at the moment but might consider switching to self-hosted at some point.
TT-RSS requires an (old, probably no longer maintained) plugin for the Fever API. FreshRSS has it built in.
Interface wise it doesn't really matter that much.
I like how TT-RSS has an API that can be integrated with mobile and native app readers so you can sync RSS feeds across multiple apps (although so far, I've only really used the mobile and their web interface).
I'll check out FreshRSS.
Update: Found this old HN thread https://news.ycombinator.com/item?id=16726998 with vague recollections of certain encounters on the bug tracker. My takeaway is the maintainer(s) didn't put too much effort into understanding some bug reports (not good but doesn't deserve the "abusive" label) and was perceived as rude (which in my experience could sometimes be attributed to lack of tact from non-native speakers). So, hard to conclusively tell without more concrete evidence.
edit: Regarding your edit, no, it isn't a language barrier. He's quick to insult people and treats feedback/contributions as opportunities to feel superior or meme (e.g., ). It's like talking to 4chan.
I switched from google reader to feedly to newsboat. One cloud service less.
While i like the idea to be able to read my feeds from multiple computers, i don't actually need it. In fact, readig them on only one device gives me back (a little bit of) focus.
And to answer my own question: No, it isn't that bad. It's fine.
Currently it's in beta testing, let me know if you find it interesting.
Which is a "port" of the very old/established python project with the same name:
If you have a server somewhere, you use cron and configure a list of feeds. Each time a new entry appears you get it sent as an email.
