I for example subscribed to Darknet Diaries on Patreon and the bonus episodes do work.
I don’t listen to more premium podcasts. I just hate that you can’t manually update the URL so far.
Also the “time listed” stats on AntennaPod are way superior, but PocketCats syncs between devices and has a web/desktop client.
You could listen to an epsiode on YouTube then pause and listen to it on YouTube music.
Would the UI also change depending on content played to expose the controls specialized for each type of media?
They already kinda do that on YouTube (with YouTube premium). When you watch a music video, you have music controls in the normal YouTube app and a button to switch to YouTube music
Tbh, they should rather make a new app called "YouTube Podcasts)

Sandboxed Google play service is actually more secure than MicroG.
it also has a Google Services compatibility that would allow you to use Google services, which would allow Google to harvest a lot of data from you
So does MicroG. Actually that’s kind of the point of both. Google play services exist to provide, well, Google play services like push notification which uses the Google servers. That’s the case with Sandboxed Google play and GrapheneOS.
OSes like CalyxOS or Lineage have microG
Yes. Pre-installed. That’s kind of a problem if you don’t want to use them in a specific profile. Also it’s quite a security issue since it needs signature spoofing to work which is insecure by definition.
has the ability to use Mozilla network location to stop google from getting that data
That alone doesn’t stop Google from getting your location data. Only not giving the your location data does this. On GrapheneOS you do this by… not enabling the location permission for any Google services including the play services.
Also by default GrapheneOS already uses GrapheneOS servers for location data and you can set your own proxy in the location settings
That’s basically everything about it. Yes, battery life is an issue on GrapheneOS with sandboxed Google play service, but well, at least it just has the permissions of a normal app. Not a privileged system app that pretends to be another app to work.

Exactly. They own the game.
Let’s plays are derivitive work. They legaly can do whatever they want with it.
Mojang also already DMCA’d people: https://youtu.be/9ARAhvFEA3s
