Podcast: Anybody archiving these? Are there any good ways to?

Given how iHeartMedia, Spotify, and Apple are all more and more invested in the podcast ecosystem it seems they are purchasing content and putting it behind a paywall. I’d like to make sure the podcasts I care about are backed up.

I saw the internet archive had a podcasts section but there wasn’t a lot of the content I’d expect to see so also interested if anyone is building a public archive
