By the way, what also helped a bit with the switch is, that all podcasts started to monetize, thus on spotify there is always only a short preview version of the podcast. Full one is usally available as a user specific rss link. This pushed me to find separate podcast solution and I am much happier with the solution I found:
#NextCloud + Gpodder sync plugin as synchronization server
NextCloud + Podcasts plugin for web browser listening on desktop
#AntennaPod for on the go listening on Android
It's #selfHosted, it's #openSource and that's what I like.
