I can’t find anything to substantiate this, think you may have dreamt it up or fell for a 4chan goof.

This is also kinda like my setup, nice!

I let audiobookshelf serve rss feeds for podcasts which I sub to in antennapod.

Same, I stuck with podcast addict for so long - once I tried antennapod I didn’t have to switch anymore. I do sync with a selfhosted gpodder though - just to not get hooked on a single app.

I’m using antennapod. It syncs to a selfhosted gpodder instance and some podcasts are hosted on my audiobookshelf. I like some exclusive podcasts from podimo but their player is shit. Selfhost a tool that creates rss feeds for those walled podimo podcasts and they get downloaded and served by audiobookshelf.
