I agree, I’ve always used sudo apt update, sudo apt upgrade and flatpak update on Pop OS and never used the pop shop.

I’m using PocketCasts and I paid a one-time fee before it became subscription based (but there’s still a free tier), in order to be able to listen to podcast using the web app on PC. Thus I now have lifetime premium access.

I’m very satisfied with their service, I did not find any problems with both the Android app and the web app, moreover it has almost every feature I need, except voice to text conversion in order to be able to share slices of audio in text format (but there are dedicated apps for that).
