I'm not sure what kind of arrangement Joe Rogan has with Spotify but my understanding is he owns his podcasts and Spotify is paying him for the exclusive right to distribute them. So what does that mean for episodes they refuse to host?
https://jremissing.com has the full list of removed episodes. Joe can fight back and just have them hosted elsewhere.
I imagine he already is talking to an attorney about it. I'll be interested to see what comes of it.
