Does the data change a lot? Does it need to be a block-based backup (e.g. bootable)? Otherwise, you could go with rsync or restic or borg to only refresh your backup copy with the changed files. This should be far quicker than taking a complete backup of the whole SSD.

Where are there ads in Apple Podcasts? I’ve never seen some. The season info is clearly shown wherever it’s relevant.

They just get rid of a bunch of so-called “fact checkers” deciding for you which posts you’re allowed to see and which get banned/hidden/deleted. It’s not the end of the world. You can still block people. You can still decide NOT to read posts.
