Yes, as far as I know they have their own podcast index and list "all" podcasts. There are some Spotify exclusive "podcasts" that are only available to Spotify users. Sure, as far as I know Spotify doesn't block the authors ads but they add ads to podcasts where there are none. The average user doesn't know that Spotify is responsible for that and might stop listening. Some podcasters intentionally publish the first episodes ad free to grow their listener base
