Yes. Self hosting tt-rss[1] and using it for close to an year now. No problem what so ever; It's so low maintenance that I would've quite possibly forgotten about it if I wasn't reading the feeds everyday. Before this I was using elfeed[2] which is a great piece of software, but I read things across various devices and elfeed had some issues with that (after all it's supposed to run inside emacs).
For podcasts (since these are also technically feeds) I use AntennaPod[3] on my Android phone, but don't use it too often because of all the time commitment required with podcasts.
I think it's mostly about drinking too much Kool-Aid of owning my data.
But probably because ttrss's pretty nice with quite a few plugins, so I can mold it based on what interests me. For example, I am also self hosting wallabag, and there's a single key shortcut to export the stuff from ttrss over to wallabag. Then there's a plugin to pull the data from the source websites and change it using XPaths. I use that to pull down the entire content instead of a single paragraph summaries, and to pull down the actual comics that I'm reading instead of the descriptions that are being sent to the readers. (As an aside, I donate/fund the makers in whatever capacity I have so that it compensates with me not getting their ads).
Did you know that even Youtube, HN & Reddit host their updates via RSS feeds? I have Youtube feeds for some of the channels that I find interesting, so that I can watch the stuff whenever it becomes available. For some low volume subreddits, you can use that as well.
With elfeed running in Emacs, I had bound a single key to download the youtube video via youtube-dl into my archive folder. I miss that stuff with ttrss, but I guess there would be some plugin somewhere to do that.
Oh, awesome, I didn't realize youtube still let you subscribe to an rss feed.
When I've self-hosted I've found I occasionally have to do maintenance that I find annoying. Most recently, I had a nextcloud server I needed to move to a bigger hard drive, which was a huge pain.
Have you just not run into those kinds of hurdles, or is it worth it to own your own data?
