It’s always good to be in control of your own content sources.
Wow, your comment took me down a rabbit hole. I now too self-host FreshRSS on my NAS using Docker. And, oh boy, this is so good!
Excellent! If you looking for an Android app - although the PWA is pretty good too, Readrops is what I use, because it supports the GoogleReader API that FreshRSS exposes.
