Spotify is trying to replace podcasts with the thing that isn't a podcast. You can decide not to listen to things that aren't podcasts, but if Spotify is successful, that may mean that podcasts you currently enjoy are no longer available in a medium you're willing to consume. That's the worry here.
I've already seen this start happening with Parcast. Since being purchased by Spotify, they're using their existing podcasts to advertise other "podcasts" that are only available streaming on Spotify. I'm guessing the ones I listen to now will eventually go away into the Spotify walled garden.
